右心室壁传导阻滞在致心律失常性右心室心肌病诊断中的地位

Effect of parietal block in diagnosis of arrhythmogenic right ventricle cardiomyopathy

目的探讨右心室壁传导阻滞(parietal block)在致心律失常性右心室心肌病(arrhythmogenic rightventricular dysplasia,ARVC)诊断标准中的适用性。方法回顾性分析可疑ARVC先证者62例的临床评估资料,项目包括性别、心电图、24 h动态心电图、超声心动图,对比分析各个诊断参数在1994、2010年欧洲心脏病学会[3]ARVC诊断标准的确诊组和可疑组间的差异。结果依据1994年标准,右心室壁传导阻滞在确诊组和可疑组间比较,差异无统计学意义[46.7%(21/45)vs.23.5%(4/17),P=0.098];而根据2010年标准,右心室壁传导阻滞在确认组和可疑组间比较,差异有统计学意义[48.9%(23/47)vs.13.3%(2/15),P=0.014]。结论右心室壁传导阻滞作为ARVC的诊断指标有待商榷。

Objectives To investigate the applicability of parietal block in diagnosis of arrhythmogenic right ventricle cardiomyopathy（ARVC）.Methods We retrospectively analyzed the data of 62 ARVC patients according to diagnosis standards of 1994 and 2009,and compared the difference of all kinds of parameter（including sexuality,electrocardiogram,24 h dynamic electrocardiogram and ultrasonic cardiography） between the final diagnosis and doubtful groups.Results It had no statistics difference of parietal block between the final diagnosis and doubtful groups according to 1994 criteria[46.7%（21/45）vs.23.5%（4/17）,P=0.098].However,It had statistics difference between two groups according to 2006 criteria [48.9%（23/47）vs.13.3%（2/15）,P=0.014].Conclusions The parietal block is controversial as one of criteria for ARVC.
