Although a relation between magni tude of ST segment elevation and myocardial damage was shown in the early period of acute myocardial infarction, such a relation among shape of the ST segment elevation, myocardial damage and elinical course remains obscure. With th is purpose 62 acute anterior MI patients who were admitted in the fi rst six hours of their first heart attack were enrolled for the study to demonstrate the relation between shape of the ST elevation prior to thrombolytic treatment and both signal-averaged ECG values detected in the early period (seventh day) of acute myocardial infaretion and el in ical course. Based on the precordial V3 derİ vation prior to thrombo lytic treatment, the shape of the ST elevation was separated into three groups as concave (n=26), straight (n=24) or convex types (n= 1 2). The re w as no statistically significant difference among groups from the points of thrombolytic treatment, endsystolic and end-diastolic volumes. Although both filtered QRS time (FQRS) and low amplitude signals (HFLA) had statistically significant differences in both groups, these were particu larly higher in the convex group. In addition root-mean square voltage of the terminal 40 ms of the f iltered-QRS (RMS40) values were quite lower in the straight and convex groups. Late potential (LP) positiveness and ventricular arrhythmia occurrence was higher in the convex group. Ventricular LP positiveness incidences were ll o/o (3/26) in the concave group, 16% (4/24) in the straight and 58% (7/12) in the convex group (pKeywords: Myocardial infarction, ST segment, signal-averaged ECG
