Left axis deviation; an electrocardiographic-pathologic correlation study.
Our understanding of the meaning of the electrocardiogram is greatly furthered by careful comparison of cardiac hypertrophy and cardiac damage observed post mortem with electrocardiograms taken during the last weeks of life. An electrocardiographic-pathologic correlation of 672 cases is reported in which the roles of left ventricular hypertrophy, myocardial infarction, and other factors in the ...
متن کاملLeft Axis Deviation
The effects of left axis shift (> -30°) on intraventricular conduction time (IVCT) were studied in 63 subjects in whom electrocardiograms before and after appearance of the left axis shift were available. Subjects with electrocardiographic evidence of left or right ventricular hypertrophy, left or right bundle branch block, myocardial infarction, pre-excitation and those receiving antiarrthythm...

متن کاملLeft axis deviation: a reassessment.
This report deals with the ramifications of the concept of left axis deviation. In early life, the leftward shift of the frontal plane QRS axis is determined chiefly, if not solely, by the relative weights of the ventricles. Once adult ventricular weight ratios are reached, there is a long period of axis stability, then a gradual leftward drift of the QRS, governed principally by left anterior ...
متن کاملTransient right axis deviation during acute anterior wall infarction or ischemia: electrocardiographic and angiographic correlation.
Eleven patients, three with acute anterior myocardial infarction and eight with anterior ischemia, who developed transient right axis deviation with a left posterior hemiblock pattern during the acute phase of myocardial infarction or ischemia are described (study group). A correlation between their electrocardiographic pattern and the angiographic findings was made. The arteriographic findings...
