Ischemic ST segment depression in leads V2-V3 as the presenting electrocardiographic feature of posterolateral wall myocardial infarction.

Abstract：

:In this study of 14 patients hospitalized with a first event of myocardial infarction, maximal ST segment depression in precordial leads V2 and V3 was the sole ECG finding during chest pain in the first 24 hours of evolving posterolateral infarction, based upon further two-dimensional echocardiographic examination and cardionuclear imaging. Other ECG findings compatible with posterolateral infarction such as the appearance of Q waves in leads V5 and V6, increased R/S ratio in leads V1 and V2, and a diminution of R wave amplitude in leads 1, aVL, V5, and V6 were relatively delayed manifestations in the majority of patients. The clinical course of all patients was benign. It therefore seems reasonable to conclude that ST segment depression in leads V2 and V3 in the absence of reciprocal ECG changes may represent the initial ECG finding of posterolateral infarction in the suitable clinical context of an acute coronary event.
