Giant negative T-wave: always coronary artery disease?

Abstract

CLINICAL CASE We describe a 82 years old patient with giant negative T waves in anterior and inferior leads at electrocardiogram (ECG) after pace-maker (PM) implantation because of total atrioventricular block, and we discuss about different cause of negative T waves at ECG. CONCLUSIONS Particularly, we remark that, after a long period of PM stimulation, a negative T waves at ECG without myocardial ischemia, defined as “electrical memory”, may appear if a spontaneous sinus rhythm occurs. The same phenomena is present in patients affected by intermittent left bundle-branch block.
