Role of QT interval at onset of acute myocardial infarction in predicting early phase ventricular arrhythmia.
In this study, the QTc interval was determined in 51 patients of acute myocardial infarction and the incidence of ventricular arrhythmias in them was noted. It was found that the QTc interval was prolonged (more than 0.44 sec) in all the 33 patients who developed ventricular arrhythmias, while it was below 0.44 sec in all the 18 patients who did not develop ventricular arrhythmia.
