Heart Rate Variability and QT Dispersion

Acute Myocardial Infarction is one of the leading causes of mortality worldwide . Arrhythmic events account for the major out of hospital mortality and also contributes significantly to the in hospital mortality. Various markers of adverse outcome in acute Myocardial infarction are in vogue and measurements of arrhythmogenic potential are believed to predict the risk in such patients. In this study we evaluated whether Heart Rate variablity and QT dispersion had prognostic significance in patients admitted with acute myocardial infarction.
