Electrophysiology of Reentrant Ventricular Arrhythmias in the Late Myocardial Infarction Period

  • Conference paper
Medical and Surgical Management of Tachyarrhythmias

Abstract

Myocardial infarction represents a highly likely source of reentrant ventricular arrhythmias. Although most studies of the early phase of ventricular arrhythmias that follow acute ligation of a major coronary artery in the dog have shown some of the basic prerequisites for reentry in the form of desynchronized slow conduction in ischemic myocardium (1–8), they all fall short of actually documenting the presence of reentry. This was due, we believe, to the highly dynamic situation following acute ligation of a major coronary artery with constantly changing electrophysiologic properties in the ischemic zone. Thus, it is difficult to conduct systematic electrophysiologic studies of the possible reentrant mechanism under such dynamic conditions. In addition, the recording techniques usually failed to demonstrate the one unequivocal evidence for reentry, namely, the presence of continuous electric activity originating from the infarction zone that regularly and predictably bridge the diastolic interval between the reentrant beat and the preceding impulse, as well as between consecutive reentrant beats, (9).
