Electrocardiographic associations of right precordial Q waves help to distinguish anterior myocardial infarction from aortic stenosis

Right precordial Q waves are ECG evidence of anterior myocardial infarction and can be present in patients with pathological left ventricular hypertrophy particularly caused by aortic stenosis. The aim of this study was to investigate the ECG features associated with Q waves in aortic stenosis and t...

Zusammenfassung:	Right precordial Q waves are ECG evidence of anterior myocardial infarction and can be present in patients with pathological left ventricular hypertrophy particularly caused by aortic stenosis. The aim of this study was to investigate the ECG features associated with Q waves in aortic stenosis and those in anterior myocardial infarction. We studied 16 patients with anterior myocardial infarction and 19 patients with aortic stenosis by means of ECG, echocardiography and clinical history. On the ECG, heart rate (70±20 beats/min vs. 83±20) and QT interval (380±65 ms vs. 390±50) did not differ between the two conditions. PR interval (160±15 ms vs. 185±30, P
