Arrhythmogenic influence of intracoronary thrombosis during acute myocardial ischemia.

Abstract

These data provide evidence that despite equal magnitudes of jeopardized myocardial mass, acute ischemia induced by thrombotic coronary occlusion results in a greater incidence of MVA than does nonthrombotic balloon occlusion. These findings suggest that the process of intracoronary thrombosis itself exerts arrhythmogenic effects above and beyond the impact of ischemia on myocardium induced by coronary occlusion.
