Abstract     The aim of the study was to determine: - whether in patients with acute myocardial infarction (AMI) the duration of the QTc interval correlates with the echocardiographically determined lett ventricular wall motion abnormality score index (WMSI) - whether patients with AMI show a correlation between the duration of the QTc interval and frequency and complexity of ventricular ectopic activity, - whether there is a correlation between the WMSI and the incidence and complexity of ventricular arrhytmias. In a series of 40 consecutive patients with a 4-day history of AMI, left ventricular WMSI and QTc intervals in ECG leads corresponding to the site of AMI, were determined. 24-hour ECGs were recorded and graded according to Lown. A statistically significant positive correlation was found between the WMSI and the QTc interval duration (r = 0,75; pc 0,001 ) especially in patients with anterior AMI (r = 0,94; pc 0,001 ). The WMSI was higher in patients with high - degree (Lown 3 - 5) ventricular ectopic activity (pc 0,05). There was no significant correlation between the duration of the QTc interval and he complexity of ventricular ectopic activity. It was concluded that the QTC interval and ventricular ectopic activity may serve as an additional indicator of impaired left ventricular systolic function. The length of the QTc interval did not correlate with the complexity of ventricular ectopic activity.
