Disturbances Of The Heart
Acute Cardiac Symptoms Acute Heart Attack
It is not proposed here to describe the condition of sudden cardiac failure, or acute dilatation during disease, or after a severe heart strain, but to describe the terrible cardiac agony which occurs, sometimes repeatedly, with many patients who ...
Acute Dilatation Of The Heart In Acute Disease
It has for a long time been recognized that in all acute prolonged illness the heart fails, sooner or later, often without its having been attacked by the disease. The prolonged high temperature causes the heart to beat more rapidly, while the toxin...
Acute Dilatation Of The Stomach
This condition is not well understood, nor is its frequence known, but not a few instances of shock are due to dilatation of this organ. The shock to the heart may be a reflex one through the pneumogastric nerves. It perhaps not infrequently occu...
Acute Mild Endocarditis
This inflammation of the endocardium is generally confined to the region of the valves, and the valves most frequently so inflamed are the mitral and aortic. There may be a slight inflammation or actual ulceration and loss of tissue. Vegetations mor...
Acute Myocarditis
Probably most acute infections cause more or less myocarditis, depending on their intensity and their prolongation. This disturbance of the heart is often unrecognized, and has been simply referred to as "the heart growing weaker from the fever proc...
Acute Pericarditis
As this inflammation is generally secondary to some other condition, its treatment cannot be positively outlined. Furthermore, it is often a terminal condition, and in such instances the results of treatment are of necessity nil. The most frequent...
Adherent Pericarditis
Following dry pericarditis or pericarditis with an exudate, especially when the exudate is fibrinous in character, the fibrous substance which is not absorbed or resorbed may develop into connective tissue, and the two pericardial surfaces become p...
Alcohol
It is rarely, if ever, advisable to use alcohol. In certain instances, however, especially in older patients who are accustomed to alcohol, a little whisky administered several times a day may act only for good, both as a food and as a peripheral di...
Alcohol
Enough has already been said of the value and limitations of alcohol as a therapeutic agent. As a beverage, when constantly used, it is liable to cause obesity, gastric indigestion, arteriosclerosis, myocardial degeneration, chronic nephritis and ci...
Alkalies
Anything which tends to increase the acidity of the tissues and to diminish the alkalinity of the blood, whether from starvation or outer causes, seems to pro-duce endocardial and myocardial irritation, if not actual inflammation. Therefore in a dis...
Altitude
It has long been known that altitude increases the heart rate and tends to lower the systolic and diastolic blood pressures; that these conditions, though actively present at first, gradually return to normal, and that after a prolonged stay at the ...
Anesthesia In Heart Disease
While no physician likes to give an anesthetic to a patient who has valvular disease of the heart, and no surgeon cares to operate on such a patient unless operation is absolutely necessary, still in valvular disease with good compensation the progn...
Angina Pectoris
This is a name applied to pain in the region of the heart caused by a disturbance in the heart itself. Heart pains and heart aches from various kinds of insufficiency of the heart, or heart weakness, are not exactly what is understood by angina pect...
Angina Pectoris Management
While a number of causes of true cardiac pain may be eliminated by improvement in any loss of compensation, by improvement of the heart tone, by more or less recovery from myocardial or endocardial inflammation, and by the withdrawal of nicotin, whi...
Angina Pectoris Symptoms
The pain of true angina pectoris generally starts in the region of the heart, radiates up around the left chest, into the shoulders, and often down the left arm. This is typical. It may not follow this course, however, but may be referred to the rig...
Aortic Insufficiency Aortic Regurgitation
This lesion, though not so common as the mitral lesion, is of not infrequent occurrence in children and young adults as a sequence of acute rheumatic endocarditis. If it occurs later in life it generally is associated with aortic narrowing, and is a...
Aortic Stenosis
Aortic narrowing or stenosis is a frequent occurrence in the aged and in arteriosclerosis when the aorta is involved. It is not a frequent single lesion in the young. If it occurs in children or young adults, it is likely to be combined with aortic ...
Aortic Stenosis Aortic Obstruction
Valvular disease at the aortic orifice is much less common than at the mitral orifice, and while stenosis or obstruction is less common from rheumatism or acute inflammatory endocarditis than is insufficiency of this valve, a narrowing or at least t...
Auricular Fibrillation Auricular Flutter
Auricular fibrillation is at times apparently a clinical entity much as is angina pectoris, but it is often a symptom of some other condition. At times auricular fibrillation is only a passing symptom, and is rapidly cured by treatment. A real auric...
Auricular Fibrillation Diagnosis
If the pulse is intermittent and there is apparently a heart block. Stokes-Adams disease should be considered as possibly present, and digitalis would be contraindicated and would do harm. A scientific indication as to whether a heart is disturbed...
Auricular Fibrillation Occurrence
This condition of auricular fibrillation occurs occasionally in valvular disease, and perhaps most frequently in mitral stenosis; but it can occur without valvular lesions, and with any valvular lesion. If it occurs in younger patients, valvular dis...
Auricular Fibrillation Pathology
Schoenberg [Footnote: Schoenberg: Frankfurt. Ztschr. f. Pathol., 1909, ii, 4.] finds that in auricular fibrillation there are definite signs in the node, such as round cell infiltration, showing inflammation, a fibrosis of the tissue, and perhaps a ...
Auricular Fibrillation Prognosis
The prognosis depends on the condition of the myocardium of the vagus. If this muscle is intact, and there is no pathologic condition in the sinus node (which can be proved by the successful results of treatment), the removal of all toxins that coul...
Auricular Fibrillation Treatment
The condition may be stopped by relieving the heart and circulation of all possible toxins and irritants, and by the administration of digitalis. One attack is frequently followed by others, perhaps of longer duration. Occasionally, however, the pat...
Baths
During rheumatism the peripheral blood vessels are generally dilated and the skin perspires profusely. This is caused not only by the rheumatism, but also by the salicylates. The surface of the body should be sponged with cold, lukewarm or hot water...
Blood Pressure
The study of the blood pressure has become a subject of great importance in the practice of medicine and surgery. No condition can be properly treated, no operation should be performed, and no prognosis is of value without a proper consideration o...
Blood Pressure And Insurance
An epitome of the consensus of opinion of the risk of accepting persons for insurance as modified by the blood pressure is presented by Quackenbos. [Footnote: Quackenbos: New York Med. Jour., May 15, 1915, p. 999.] Some companies have ruled that at ...
Blood Pressure In Children
May Michael, [Footnote: Michael, May: A Study of Blood Pressure in Normal Children, Am. Jour. Dis. Child., April, 1911, p. 272.] after a study of the blood pressure in 350 children, came to the conclusion that the blood pressure in children increase...
Bradycardia
The first decision to be made is what constitutes a slow pulse or slow heart. A pulse below 58 or 60 beats per minute should be considered slow, and anything below 50 should be considered abnormally slow and a condition more or less suspicious. A pu...
Bradycardia Symptoms
If a person has been long accustomed to a slow-acting heart, there are no symptoms. If the heart has become slowed from disease or from any acute condition, the patient is likely to feel more or less faint, perhaps have some dizzines, and often head...
Bromids And Chloral
If there is much restlessness and the circulation is good, that is, if myocarditis is probably not present, the bromids may be of great value, especially in children. The dose should be sufficient to quiet the nervous system. The drug may be discont...
Caffein
Caffein can irritate the heart and cause irregularity and tachycardia, especially in certain persons. In fact, some can never take a single cup of coffee without having an attack of palpitation, and many times when coffee and tea have been unsuspect...
Cardiac Disease In Pregnancy
It is so serious a thing for a woman with valvular lesion or other cardiac defect to become pregnant that no young woman with heart disease should be allowed to marry. Perhaps every normal heart during pregnancy hypertrophies somewhat to do the extr...
Cardiac Drugs
Whether any drug should be used which acts directly on the heart is often a question for decision. As endocarditis is generally secondary to some acute disease, the patient has become weakened already, and the circulation is not sturdy; therefore su...
Cardiovascular Renal Disease
With the strennousness of this era, this disease or condition, which may be regarded as one of the accompaniments of normal old age, has become of grave importance, and nowadays frequently develops in early middle life. If it is diagnosed in its i...
Cardiovascular Renal Disease Arrhythmia
While this terns really signifies irregularity and intermittence of the heart, it may also be broadly used to indicate a pulse which is abnormally slow or one which is abnormally fast, a rhythm which is trot correct for the age, condition and acti...
Cardiovascular Renal Disease Treatment
While it is urged, in preventing the actual development of this disease, and in slowing its progress, that it is advisable to lower a high blood pressure, we must remember that this blood pressure mad be compensatory, and many times should not be mu...
Chronic Endocarditis
It is not easy to decide just whew all acute endocarditis has entirely subsided and a chronic, slow-going inflammation is substituted. It would perhaps be better to consider a slow-going inflammatory process subsequent to acute endocarditis as a sub...
Chronic Myocarditis Fibrous
Chronic myocarditis may develop on an acute myocarditis, but is generally a slowly progressive chronic process from the beginning; it occurs mostly in persons past middle life, and as a rule is not primarily associated with rheumatism or valvular di...
Classification Of Cardiac Disturbances
For the sake of discussing the therapy of cardiac disturbances in a logical sequence, they may be classified as follows: Pericarditis Acute Adherent Myocarditis Acute Chronic Fatty Endocarditis Acute, sim...
Clinical Interpretation Of Pulse Tracings
A moment may be spent on clinical interpretation of pulse tracings. It has recently been shown that the permanently irregular pulse is due to fibrillary contraction, or really auricular fibrillation--in other words, irregular stimuli proceeding from...
Conditions Causing Change In Blood Pressure
Woolley [Footnote: Woolley, P. G.: Factors Governing Vascular Dilatation and Slowing of the Blood Stream in Inflammation, THE JOURNAL A. M. A., Dec. 26, 1914, p. 2279.] quotes Starling as finding that the blood vessels dilate from physical and chemi...
Convalescence
When compensation has been restored, the patient may be allowed gradually to resume his usual habits and work, provided these habits are sensible, and the work is not one requiring severe muscular exertion. Careful rules and regulations must be laid...
Coronary Sclerosis
While disease of the coronary arteries may occur without general arteriosclerosis, it is so frequently associated with it that it is necessary to give a brief description of the general disease. Arteriosclerosis or arteriocapillary fibrosis is rea...
Decompensation
To understand the physiology, pathology and the best treatment for broken compensation, it is necessary to study the physics of the circulation under the different conditions. With the mitral valve insufficient, a greater or less amount of blood is ...
Diagnosis
If a more malignant form of endocarditis develops on a mild endocarditis, the diagnosis is generally not difficult. If, without a definite known septic process, malignant endocarditis develops, localized symptoms of heart disturbance and cardiac sig...
Diet
As intimated in the preceding paragraph, the diet during endocarditis must be carefully regulated. It must be sufficient, and appropriate for the disease in which the complication occurs, but it must be in such dosage and administered with such freq...
Diet And Baths In Heart Disease
The diet in cardiac diseases has already incidentally been referred to. The decision as to what a patient ought to eat or drink must often be modified by just what the patient will do, and, as we all know, it is absolutely necessary to make some c...
Disturbances Of The Heart In General
Of prime importance in the treatment of diseases of the heart is a determination of the exact, or at least approximately exact, condition of its structures and a determination of its ability to work. This is not the place to describe its anatom...
Drugs In Hypertension
The drugs that are mostly used to lower blood pressure are nitrites or drugs which are like nitrites, and these are nitroglycerin, sodium nitrite, erythroltetra nitrate and amyl nitrite, and the frequency of their use is in the order named. Other dr...
Emergencies
5. Cardiac Emergency Drugs.--Besides some of the drugs already mentioned (such as camphor hypodermically, nitroglycerin when indicated, strophanthin hypodermically or intravenously, caffein and strychnin), often ergot, suprarenal vasopressor princip...
Endocarditis
It should be understood that especially in acute conditions a positive separation of endocarditis from myocarditis is incorrect. Acute endocarditis can probably not occur without some inyocarditis, and myocarditis probably does not occur without s...
Endocarditis A Secondary Affection
Mild endocarditis is rarely a primary affection, and is almost invariably secondary to one of the diseases named above. Nearly 75 percent of secondary endocarditis occurs as a complication of acute articular rheumatism and chorea, or subsequently. O...
Etiology
One of the most common causes of hypertension is clue to excess of eating and drinking. The products caused by maldigestion of proteins, and the toxins formed and absorbed especially from meat proteins, particularly when the excretions are insuffici...
Etiology
Rheumatism is the cause of most instances of cardiac disease which date back to childhood or youth, while arteriosclerosis and chronic infection cause most cardiac diseases in the adult. In the former case it is the mitral valve which is the most fr...
Etiology
The cause of an irregularly acting heart in an adult may be organic, as in the various forms of myocarditis, in broken compensation of valvular disease, Stokes-Adams disease, coronary disease, auricular fibrillation, auricular flutter, cerebral dise...
Etiology Pathology
If a chronic endocarditis has followed an acute condition, some slight permanent papillomas or warty growths may he left from the healed granulating or ulcerated surfaces. Sometimes these little elevations on the valves become inflamed and then adhe...
Etiology Treatment
A subacute or a chronic infective endocarditis should be treated on the same plan as an acute endocarditis, which means rest in bed and whatever medication seems advisable, depending on the supposed cause of the condition. A chronic endocarditis ...
Etiology Treatment
One has but to refer to the enumerated causes of irregular heart action to determine the treatment. In that caused by extrasystole, the treatment has just been suggested. In irregular heart caused by serious cardiac or other lesions the treatment ha...
Factors Increasing The Blood Pressure
With normal heart and arteries, exertion and exercise should increase the systolic pressure, and generally somewhat increase the diastolic pressure. The pressure pulse should therefore be greater. When there is circulatory defect or abnormal blood p...
Fatty Degeneration
Fatty degeneration of the heart muscle may be caused by acute poisoning (as phosphorus, arsenic, etc.), by serious infections, or it may follow fibrosis of the heart or coronary artery disease. The symptoms are those of serious circulatory weaicnens...
Fatty Heart
The cause of deposits of fat around the heart or in between its chambers is the same as the cause of general obesity. These patients are likely to be obese, or at least to have large abdomens with large deposits of fat around the abdomen. This fat i...
Heart Disease In Children And During Pregnancy
A common characteristic in a large proportion of middle-aged or old patients with heart disease is the presence of degenerative changes in the myocardium, the valves, or the arteries of the heart. In children, on the other hand, the most common di...
Hypertension
Arterial hypertension may be divided into stages. In the first stage the arteries are healthy, but the tone, owing to contraction of the muscular walls, is too great. This condition or stage has been termed "chronic arterial hypertension." This co...
Hyperthyroidism
The presence of a well marked case of exophthalmic goiter is not necessary for the secretion of the thyroid to be increased sufficiently to cause tachycardia; in fact, an increased heart rapidity in women often has hyperthyroidism as its cause. The ...
Hypotension
A low systolic pressure and a low diastolic pressure may not cause any symptoms or give any cause for anxiety. It does show, especially if the systolic pressure is below normal for the age of the person, a lack of reserve power, and such patients ...
Indications For Strychnin
Strychnin is a much overused drug. It is now given for almost everything and during almost every disease. It is true that the administration of strychnin is largely due to the evolution of the age in which we are now living. We have ceased to purge ...
Interpretation Of Tracings
The interpretation of the arterial tracing shows that the nearly vertical tip-stroke is due to the sudden rise of blood pressure caused by the contraction of the ventricles. The long and irregular down-stroke means a gradual fall of the blood pressu...
Intestinal Putrefaction
The most successful procedure in the management of intestinal putrefaction is to remove meat from the diet absolutely. Laxatives in some form are generally indicated, and one of tile best is agar- agar. Of course aloin and cascara are always good la...
Iron
It is essential for the welfare of the patient, especially after a long illness before the complication of endocarditis could occur, and in rheumatic fever, in which all meat and meat extractives have been kept from the diet, that small doses of iro...
Laxatives
If the bowels are known to be in excellent condition and not loaded with fecal matters, brisk catharsis is not needed simply because endocarditis has developed. If the bowels have been neglected, a small dose of calomel, aided by a compound aloin ta...
Malignant Endocarditis Ulcerative Endocarditis
Since we have learned that bacteria are probably at the bottom of almost any endocarditis, the terms suggested under the classification of endocarditis as "mild" and "malignant" really represent a better understanding of this disease. They are not ...
Mitral Insufficiency: Mitral Regurgitation
This is the most frequent form of valvular disease of the heart, and is due to a shortening or thickening of the valves, or to some adhesion which does not permit the valve, to close properly, and the blood consequently regurgitates from the left ve...
Mitral Stenosis: Mitral Narrowing
This particular valvular defect occurs more frequently in women than in men, and between the ages of 10 and 30, and is generally the result of rheumatic endocarditis or chorea, perhaps 60 percent of mitral stenosis having this origin. Other causes a...
Myocardial Disturbances
While the myocardium is the most important muscle structure of the body, it has but recently been studied carefully or well understood clinically or pathologically. A heart was "hypertrophied" or "dilated" or perhaps "fatty." It suffered from "pai...
Myocarditis Fibrous Management
The advice he should receive is well understood: to avoid physical efforts; to avoid mental tire; to avoid overeating or overdrinking of any foods or liquids; to reduce or abstain from alcohol, coffee, tea and tobacco, depending on what seems advisa...
Myocarditis Fibrous Symptoms And Signs
The symptoms of chronic myocardial degeneration are progressive weakness, slight at first, noticeable on exertion (and what was not considered exertion becomes such), as evidenced by slight palpitation, slight shortness of breath, leg weariness and ...
Nauheim Baths
At Nauheim, under the direction of Dr. Theodore Schott, baths form an important part of the treatment. These baths are of two kinds, the saline and the carbonic acid. The medicinal constituents of the saline bath are sodium chlorid and calcium chlor...
Normal Blood Pressure For Adults
Woley [Footnote: Woley, II. P.: The Normal Variation of the Systolic Blood Pressure, THE JOURNAL A. M. A., July 9, 1910, p. 121.] after studying, the blood pressure in a thousand persons, found that the systolic average for males at all ages was 127...
Opium
As so many times repeated, real pain must be stopped, and morphin, either by the mouth or hypodermically, should be used to the point of stopping such pain. If the patient is a young child, codein sulphate or the deodorized tincture of opium may be ...
Other Lesions
Tricuspid insufficiency, except as rarely found in the fetus, is generally due to a relative insufficiency rather than to an actual disease of the tricuspid valve. In other words, if the right ventricle dilates the valve may be insufficient. Tricusp...
Paroxysm Drugs
The part the nervous system plays in this paroxysm is shown by the good result obtained from injections of morphin, even when there is no pain; hence the action of morphin is directly in line with the natural resolution of the symptoms: it quiets th...
Paroxysm Management
The immediate conditions to meet are the rapid fluttering heart, the nervous excitation and cardiac anxiety, and perhaps the most important of all, the vasomotor spasm that is often so pronounced. Physically we have, then, a heart with leaking or co...
Paroxysmal Tachycardia
This condition is generally termed by the patient a "palpitation," and palpitation of the heart is recognized by most physicians as meaning a too rapidly acting heart, the term "tachycardia" being reserved for an excessive rapidity of the heart. Man...
Paroxysmal Tachycardia Management
There is no specific treatment for paroxysmal tachycardia. What is of value in one patient may be of no value in another; in fact, drugs are rarely successful in ameliorating or preventing the condition. Patients who are accustomed to these attacks ...
Pathologic Physiology
The development of permanent injury to one or more valves of the heart may have been watched by the physician who cares for a patient with acute endocarditis, or it may have been noted early during the progress of arteriosclerosis or other conditi...
Pathology
The part of the heart most affected is the part which has the most work to do--the left side of the heart--and of this side the left ventricle and therefore the mitral and aortic valves; the most frequent valve to be inflamed and to stiffer permanen...
Pathology
The pathology of arteriosclerosis is a thickening and diminishing elasticity of the arteries, beginning with the inner coat and gradually spreading and involving all the coats, the larger arteries often developing calcareous deposits or thickened ca...
Pericarditis Symptoms And Signs
If there is pain or much aching in the cardiac region, it tends to disappear with the exudate, if such is to occur, in the same way as does the pain of pleurisy. If there is much exudate, the pressure on the heart of course increases, the cardiac du...
Physics Of Aortic Lesions
Next in frequency to mitral insufficiency is aortic insufficiency, which occurs most frequently in men. The cavity of the heart that is most affected by this lesion is the left ventricle, which receives blood both from the left auricle, and regurgit...
Physics Of Mitral Stenosis
Mitral stenosis, though less common than mitral regurgitation, is a frequent form of disease of the valves, especially in women. Often this condition is associated with regurgitation; but in a simple mitral stenosis the greatest hypertrophy is of ne...
Precautions To Be Observed
As long as compensation is complete, there are no medication and physical treatment necessary for the damaged heart. The patient, however, should be told of his disability, and restrictions in his habits and life should be urged on him. The most imp...
Prevention
If the patient is weak, the circulation depressed, the blood pressure low, and the heart rapid, the drug advisable to produce rest and sleep is almost always morphin or some other form of opium. Morphin, with few exceptions, is a cardiac tonic and a...
Prognosis
Janeway [Footnote: Janeway, T. C.: A Clinical Study of Hypertensive Cardiovascular Disease, Arch. Int. Med., December, 1913, p. 755.] presented statistics of 458 patients with high blood pressure, 67 percent of whom were men. Of these 458 patients 2...
Prognosis And Convalescence
The duration of acute endocarditis varies greatly; it may be two or three weeks, or the inflammation may become subacute and last for several months. Although mild endocarditis rarely causes death of itself, it may develop into an ulcerative endocar...
Pseudo-angina
While this name is more or less unfortunate, it has long been in vogue as a designation for pains and disturbances referred by a patient to his heart. Therefore with the distinct understanding that if the diagnosis is correct the name is a misnomer,...
Pulmonary Insufficiency Pulmonary Regurgitation
If this rare condition occurs, it is probably congenital. A distinctive murmur of this insufficiency would be diastolic and accentuated in the second intercostal space on the left of the sternum. It should be remembered that aortic murmurs are often...
Pulmonary Stenosis Pulmonary Obstruction
If stenosis is actually present in this location, the lesion is probably congenital. It might occur after a serious acute infectious endocarditis, but then it would be associated with other lesions of the heart. It has been found to be associated wi...
Pulsus Alternans
By this term is meant that condition of pulse in which, though the rhythm is normal, strong and weak pulsations alternate. White [Footnote: White: Am. Jour. Med. Sc., July, 1915, p. 82.] has shown that this condition is not infrequent, as demonstrat...
Shock
The treatment of shock will probably always be unsatisfactory as the cause is so varied, and, although circulatory prostration and vasomotor paresis always constitute the acute condition, the physiologic health of the heart and blood vessels is so v...
