心房纤颤和室上性心动过速可因来自对侧束支的冲动反复逆向隐匿传导引起持续性束支传导阻滞,这一现象被称之为“蝉联”,类似的情况也可发生在旁道。为检验这一推测,作者观察了10例预激综合征患者的电生理改变。方法全部患者都有反复发作的心律失常,4例房颤,6例顺向性心动过速;7例服用抗心律失常药物。4例用食道程序心房起搏,余均做心内电生理检查。用递减、递增心房起搏评估正常与旁道传导。起搏周长递减,
Atrial fibrillation and supraventricular tachycardia may be due to the impulse from the contralateral bundle branch repeatedly hidden reverse conduction caused by persistent bundle branch block, a phenomenon called “reelection,” a similar situation can occur next Road. To test this hypothesis, the authors observed electrophysiological changes in 10 patients with Wolff-Parkinson-White syndrome. Methods All patients had recurrent arrhythmias, 4 cases of atrial fibrillation, 6 cases of tachycardia and 7 cases of antiarrhythmic drugs. 4 cases of atrial pacing with esophageal procedures, I still do intracardiac electrophysiological examination. With decreasing, increasing atrial pacing assessment of normal and bypass conduction. Paced circumference decreased,
