Abstract: 

According to recent researches about the importance of prognostic value of QT dispersion (QTD) in patients with acute myocardial infarction, the present study was performed to assess the relationship between QT dispersion increment and incidence of ventricular fibrillation in patients with acute myocardial infarction.
QT dispersion was calculated by caliper in the first 24 hour's ECG after acute myocardial infarction in 30 cases of AMI that complicated by ventricular fibrillation and was compared with 200 cases without ventricular fibrillation. Also some information about primary or secondary VF, EF (according to echocardiography) was recorded in check list. The study was a descriptive, cross - sectional study.
Direct relationship between QT increment and mechanical dysfunction of left ventricle (EF<40%) was showed. In patients with primary VF the mean of QTD was 20 msec more than the patients with secondary VF. In patients with acute myocardial infarction (AMI) that complicated with VF the QTD was greater than the patients without VF.
According to above results we can use QTD as a cheap, easy and available method for diagnosis of increased incidence of VF in patients with AMI.
