预激综合征合并心房颤动(AF)为心内科急症,发作时可导致快速的心室率,严重者可导致心室颤动、猝死,进一步理解其发生机制对临床处理及防治有重要意义。近年研究表明,预激综合征合并AF的发生机制可能与旁路电生理特性、旁路对心房电生理特性的影响和旁路逆传致波峰碰撞等因素有关。 WPW syndrome combined with atrial fibrillation (AF) is a cardiology emergency, which can lead to rapid ventricular rate, severe cases can lead to ventricular fibrillation, sudden death, further understanding of its mechanism of clinical treatment and prevention is important. In recent years, studies have shown that pre-excitation syndrome with AF may be related to the mechanism of bypass electrophysiological characteristics of the bypass on the electrophysiological characteristics of atrial and adverse effects caused by the bypass wave crest collision and other factors.
