The electrocardiograms of patients in whom myocardial infarction was excluded at autopsy are presented to bring out (1) the following features of left bundle branch block suggesting anteroseptal infarction—QS or qrS patterns in leads from the right precordium or localized to intermediate leads and/or cove plane inversion of the T waves near the transitional zone; (2) the following features of right bundle branch block suggesting infarction—pseudo Q waves, elevated RS-T segments and inverted T waves in right precordial leads, prominent Q waves in leads from the left precordium.
