Abstract
Despite substantial gains in our understanding of the electrophysiologic effects of antiarrhythmic drugs, the mechanism(s) responsible for their clinical efficacy remains elusive. The purpose of this discussion is to examine what is known about the mechanism of antiarrhythmic drug action in the treatment of clinical reentrant arrhythmias. Ventricular tachycardia in the setting of healed myocardial infarction will serve as the focus for the discussion as: (a) the reentrant mechanism of this arrhythmia is well established [1, 2], and (b) the effect of antiarrhythmic drugs on the individual components of the circuit is more difficult to determine than in macroreentrant arrhythmias such as AV reentry or AV nodal reentry. In this sense, the determination of antiarrhythmic mechanisms for VT is more difficult, but also more fundamental, than for macroreentrant rhythms because the vulnerable parameter [3] is not as evident.
