摘　　要：目的探讨国人致心律失常性右心室心肌病患者临床心电图特征。方法分析32例致心律失常性右心室心肌病患者体表心电图各项参数。结果心电图记录到Epsilon波12例，QRS时间（V1＋V2＋V3）／（V4＋V5＋V6）≥1.2共15例，终末激动时间延长17例，出现QRS波群碎裂23例，可见异常Q波8例，V1～V3T波倒置且不存在束支传导阻滞14例，完全性右束支传导阻滞3例，不完全性右束支传导阻滞1例。28例记录到室性心动过速。结论Epsilon波、QRS时间（V1＋V2＋V3）／（V4＋V5＋V6）≥1.2、终末激动时间延长≥55ms及QRS波群碎裂是致心律失常性右心室心肌病特征性的体表心电图改变。Objective To analyze the electrocardiographic （ECG） features of arrhythmogenic right ventricular cardiomyopathy （ARVC）. Methods ECG parameters were analyzed in 32 patients with ARVC. Results Epsilon wave was appeared in 12 cases, ratio of QRS duration in leads （ V1 ＋V2 ＋V3） / （ V4 ＋V5 ＋V6） ≥1.2 in 15 cases, terminal activation duration ≥55ms in 17 cases, fragmented QRS in 23 cases, abnormal Q wave in 8 cases, T wave inversion without left bundle branch block in V1 -V2 in 14 cases, complete right bundle branch block in 3 cases and incomplete right bundle branch block in one case. Ventricular tachycardia was documented in 28 cases. Conclusion Epsilon wave, the ratio of QRS duration in leads （V1 ＋V2 ＋V3） / （V4 ＋V5 ＋V6）≥ 1.2, terminal activation duration ≥55ms and fragmented QRS complex are characteristic ECG findings of ARVC.
