NCT00145119

Brief Summary

The purpose of this study is to assess the incidence of tachy- and bradyarrhythmic episodes in patients with acute myocardial infarction with depressed ventricular function and to determine the predictive value of several invasive and non-invasive risk markers for life-threatening arrhythmia
