Predicting Atrial Fibrillation After Mitral Valve Replacement

摘要

Inhomogeneous prolongation of sinus impulses may predict the recurrence of atrial fibrillation (AF). Chang et al. investigated the relationship between P‐wave characteristics and AF development following cardiac coronary surgery (CCS). The paper presented by Balcetyte‐Haris gave us important information about the prevention on post‐CCS AF, and showed that esmolol offered no advantages to standard beta‐blockers in preventing AF after CCS in the patients with prolonged signal‐averaged ECG P‐wave duration. The data on AF occurrence, antiarrhythmic drugs and P‐wave analysis are limited. In a study we observed that amiodarone, and decreasing P‐wave dispersion detected by surface ECG, would improve the maintenance of sinus rhythm (SR) in patients with paroxysmal AF.
