[Effect of antiarrhythmic therapy on late potentials].
The purpose of this paper is to review the presently available information on the effect of antiarrhythmic therapy (medical treatment, catheter ablation and surgery) on ventricular late potentials (LP). Therapeutic efficacy of sustained ventricular tachycardia (SVT) is thought to be prevention of it or changing to hemodynamical stable SVT due to prolongation of cycle length of SVT. No significant correlation between LP and inducibility or suppression of SVT was observed. Prolongation of cycle length of SVT is thought to be related to increase of LP. Correlation between LP and efficacy of catheter ablation is thought to be controversial. LP is thought to be diminished after successful antiarrhythmic surgery.
