A 12-lead ECG-method for quantifying ischemia-induced QRS prolongation to estimate the severity of the acute myocardial event.INTRODUCTION

ECG-method
QRS duration was estimated in the lead that showed the maximal ST deviation according to a novel method. 
QRS duration was estimated in the lead that showed the maximal ST deviation according to a novel method.
The degree of prolongation was determined by subtracting the measured QRS duration in the lead that showed the least ST deviation.
