Interpretation Of Tracings
Source: Disturbances Of The Heart
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 pressure. The first
upward rise in this gradual decline is due to the secondary
contraction and expansion of the artery; in other words, a tidal
wave. The second upward rise in the decline is called the recoil, or
the dicrotic wave, and is due to the sudden closure of the aortic
valves and the recoil of the blood wave. The interpretation of the
jugular tracing, or phlebogram as the vein tracing may be termed,
shows the apex of the rise to be due to the contraction of the
auricle. The short downward curve from the apex means relaxation of
the auricle. The second lesser rise, called the carotid wave, is
believed to be due to the impact of the sudden expansion of the
carotid artery. The drop of the wave tracing after this cartoid rise
is due to the auricular diastole. The immediate following second
rise not so high as that of the auricular contraction is known as
the ventricular wave, and corresponds to the dicrotic wave in the
radial. The next lesser decline shows ventricular diastole, or the
heart rest. A tracing of the jugular vein shows the activity of the
right side of the heart. The tracing of the carotid and radial shows
the activity of the left side of the heart. After normal tracings
have been carefully taken and studied by the clinician or a
laboratory assistant, abnormalities in these readings are readily
shown graphically. Especially characteristic are tracings of
auricular fibrillation and those of heart block.
