Abstract:
Forty consecutive patients (pts) with acute myocardial infarction (MI) who survived to be discharged from the hospital were studied with high gain signal averaged electrocardiography (SAECG). 28% of the pts with non-Q MI had an abnormal SAECG as compared to 15% in the Q MI group. It was also found that SAECG showed a significantly longer filtering QRS duration in the non-Q MI group. The results above were considered as indicative of more delayed activation in pts with non-Q MI providing probably a substrate for more frequent reentrant arrhythmias.
