大多数WPW综合征病人自发房颤的机理尚不清楚。一些研究结果提示电生理试验中出现的房室折返性心动过速可转变成房颤。作者对342例预激综合征手术后作长期随访以观察手术对房颤的影响。研究对象包括1968年12月至1986年11月入院作旁路切除术的342例WPW综合征病人。手术前作电生理试验。试验前停用抗心律失常药物5个半衰期。测定旁路和正常房室通导的正向、逆向传导,房室传导,旁路传导,心房和心室在各种起搏频率时的不
The mechanism of spontaneous atrial fibrillation in most patients with WPW syndrome is not clear. Some studies suggest that atrioventricular reentrant tachycardia that occurs in electrophysiological tests can be converted to atrial fibrillation. The authors of 342 cases of pre-excitation syndrome after long-term follow-up to observe the impact of surgery on atrial fibrillation. Participants included 342 patients with WPW syndrome admitted to bypass from December 1968 to November 1986. Electrophysiological test before surgery. Five half-lives of anti-arrhythmic drugs were discontinued before the trial. Determination of bypass and normal atrioventricular conduction of the forward, reverse conduction, atrioventricular conduction, bypass conduction, atrial and ventricular in a variety of pacing frequency
