【摘要】 [目的]探讨间歇性预激综合征的形成机制。[方法]回顾性分析50例间歇性预激综合征的心电图。[结果]该病常见的形成原因为:①房室旁道频率依赖性传导阻滞;②旁道内隐匿性传导及“蝉联现象”;③旁道裂隙现象;④旁道2:1传导阻滞;⑤沃-帕-怀综合征患者合并交接区性期前收缩等异位心律。[结论]深入理解上述心电现象对诊断间歇性预激综合征及其它心律失常均有较大指导意义。更多还原

【Abstract】 Objective Explore the mechanism of intermittent pre-excitation syndrome(IPS). Method Trace back and analyze ECG of 50 cases of IPS. Result The common causes of the disease: ①AV by-pass independent efferent block;②by-pass latent conduction and “cicada combination”; ③by-pass crack; ④by-pass 2:1 conduction block;⑤Wo-Pa-Huai syndrome and ectopic cardiac rhythm of copulatory zone premature beat. Conclusion A good understanding of the ECGs above is of great meaning to diagnose IPS and other arrhythmia.更多还原
