目的:分析8例以晕厥及右束支传导阻滞(RBBB)为首发表现的高度房室传导阻滞患者的临床特征及治疗效果。方法:回顾性分析于1999年1月至2009年12月间以晕厥原因待查而在我院接受住院治疗的连续217例患者的病历资料。结果:217例患者入院心电图呈现完全性右束支传导阻滞(CRBBB)有33例(15.2%)。该33例患者在后续的1次或多次动态心电图检查中,有8例(24.2%)检出有一过性Ⅱ°或高度房室传导阻滞。8例患者均行起搏器置入治疗,术后随访(104±8.9)个月,所有患者晕厥症状均消失。结论:对于心电图表现为RBBB的晕厥患者需要进一步排除高度或Ⅲ°房室传导阻滞的可能性。
OBJECTIVE: To analyze the clinical features and therapeutic effects of 8 patients with highly atrioventricular block who had syncope and right bundle branch block (RBBB) as the first manifestation. Methods: The clinical data of 217 consecutive patients who were hospitalized in our hospital from January 1999 to December 2009 with the cause of syncope were retrospectively analyzed. Results: There were 33 cases (15.2%) of 217 patients presenting with complete right bundle branch block (CRBBB) on admission electrocardiogram. Of 33 patients who underwent one or more follow-up Holter tests, 8 (24.2%) had transient IIR or atrioventricular block. All 8 patients underwent pacemaker implantation. All patients were followed up for a mean of (104 ± 8.9) months. The symptoms of all patients disappeared. Conclusion: Patients with syncope with RBBB on ECG need further exclusion of height or atrioventricular block.
