THE CARDIOGRAM IN VENTRICULAR ANEURYSM FOLLOWING CARDIAC INFARCTION

Abstract

The 4 essential features are (1) the presence of QS waves in 1 or more chest leads (excluding VI); (2) inversion of the T wave, or its incorporation in the elevated RS-T segment, in at least 3 of the unipolar chest leads; (3) the presence of a deep S wave in lead VF, at least 5 mm. in depth, and consequently in standard leads II and III also; (4) inversion of the T wave in VL and therefore in lead I. Two other very common but not essential points are persistent elevation of the RS-T segment in unipolar chest leads and the presence of a Q wave in VL and in lead I. These were the findings in 18 out of 24 anterior aneurysms. No ecg. diagnostic signs were found in posterior aneurysms.
