Abstract

Cardiac memory is an electrocardiographic manifestation of transient T wave abnormalities, which is observed after abrupt interruption of abnormal ventricular activation. We report a case with preexisting complete left bundle branch block in whom cardiac memory was induced. This cardiac memory was induced by normalization of QRS morphology after development of complete atrioventricular block due to acute inferior myocardial infarction. <
