Comparison of Q with non-Q myocardial infarction using signal averaged ECG.
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.
