Do QRS duration and QT peak prolongation predict death or nonfatal MI in patients with suspected coronary disease referred for elective cardiac catheterization?
Simple ECG parameters, specifically QRS duration and QT peak, are independent predictors of death or nonfatal MI in stable patients undergoing coronary angiography.
Wong et al. (2008) studied this question.
