摘　　要：目的探讨房室交界性逸搏心律伴束支及分支内文氏现象的心电图表现、诊断的可行性及临床意义。方法对7例房室交界性逸搏心律伴束支及分支内文氏现象的常规心电图进行回顾性分析。结果患者的心电图特征包括:①窦性心律、心房颤动时伴完全性/高度房室或窦房阻滞;②心室节律是起源于房室交界区的逸搏心律,节律匀齐;③逸搏的QRS波周期性出现正常形态,之后继以束支阻滞逐渐加重的图形。结论束支及分支内文氏现象是少见的心电现象,可以通过体表心电图做出诊断,其临床预后较差,需积极采取诊治措施。Objective To explore the Electrocardiogram（ECG）features,the diagnosis feasibility and clini-cal significance of atrioventricular junctional escape rhythms by bundle branch and fascicular Wenckebach＇s phenomenon.Methods ECGs were analyzed retrospectively in 7 patients with atrioventricular junctional escape rhythms by bundle branch and fascicular Wenckebach＇s phenomenon.Results The ECGs had the following fea-tures：①Sinus rhythm or atrial fibrilliation is along with complete/high degree atrioventricular or sinoatrial block; ②Ventricular rhythm is a escape rhythm originated from atrioventricular junctional area,with evenly rhythm;③ Periodicity presents itself to normal morphology of escape QRS waves,with bundle branch block gradually aggra-vating.Conclusion The infrequent ECG phenomena of bundle branch and fascicular Wenckebach＇s phenomenon can be diagnosed by surface ECG,which indicates a pessimistic prognosis.Some effective diagnostic and thera-peutic approaches should be taken timely.
