transient entrainment was used to test the hypotheses that 1 ) procainamide prolongs the cycle length of ventricular tachycardia in patients with coronary artery disease because it has a preferential effect on the reentrant tachycardia circuit , and 2 ) regions of slow conduction in the reentrant circuit are more susceptible to the effect of procainamide than are other areas of the ventricles .
