摘要
目的探讨致心律失常性右室心肌病(ARVC)患者的心电图aVR导联特征。方法分析60例ARVC患者的体表心电图aVR导联的波形特征,并与71例正常人心电图作对照。结果 ARVC患者aVR导联呈QR型、rSr型及rSR型的比例明显高于对照组(分别为23.3%vs 5.6%,26.7%vs 8.5%,6.7%vs 0,P<0.01);而呈Qr型者所占的比例明显低于对照组(13.3%vs 46.5%,P<0.01),与对照组相比ARVC患者aVR导联呈碎裂QRS波明显增多(33.3%vs 8.5%,P<0.01);ARVC患者aVR导联Q波或S波振幅减小(0.42±0.26 mV vs 0.62±0.25 mV,P<0.01);且R/S比值明显增大(0.52±0.67 vs 0.21±0.23,P<0.01)。结论 ARVC患者的体表心电图aVR导联特征性改变可作为ARVC的诊断线索。
Objective To investigate the characteristics of electrocardiographic（ECG） lead aVR in patients with arrhythmogenic right ventricular cardiomyopathy（ARVC）.Methods The lead aVR of ECG waveform features were analyzed in 60 cases of patients with ARVC,and 71 cases with normal ECG as the control group.Results The ECG lead aVR in patients with ARVC showed QR type,rSr type and rSR type was significantly higher than the proportion of the control group（respectively 23.3% vs 5.6%,26.7% vs 8.5%,6.7% vs 0,P0.01）;and showed Qr type was significantly lower than the proportion of the control group（13.3% vs 46.5%,P0.01）,Fragmented QRS wave（fQRS） of lead aVR in the ARVC group compared with the control group was significantly increased（33.3% vs 8.5%,P0.01）.The Q wave or S wave amplitude of lead aVR in the ARVC group was decreased（0.42±0.26 mV 0.62±0.25 mV,P0.01）;and R/S ratio was significantly increased（0.52±0.67 vs 0.21±0.23,P0.01）.Conclusion The characteristic ECG changes of lead aVR in patient with ARVC can be used as clues to the diagnosis of ARVC.
