摘　　要：目的探讨致心律失常性右心室心肌病(arrhythmogenic right ventricular dysplasia/cardiomyopathy,ARVD/C)合并室性心动过速与心室晚电位的关系。方法ARVD/C38例,男28例,女10例,年龄(35±15)岁。心电图检查进行信号叠加,记录心室晚电位量化参数:总QRS时限(total QRS duration,QRST)、QRS终末部位电压低于40μV时限(low potential terminal signals,LPS40)、QRS最后40ms电压方根均数(root mean square of the last 40 ms,RMS40);动态心电图检查记录室性心动过速和室性期前收缩。使用χ2及Mann-Whitney秩和检验统计。结果①心室晚电位阳性25例,其中室性心动过速18例;心室晚电位阴性13例,室性心动过速3例(P=0.004);②室性心动过速阳性21例,阴性17例,QRST:室性心动过速阳性组109～233(中位数147)ms,阴性组85～158(中位数104)ms(P=0.000);LPS40:阳性组15～158(中位数53)ms和阴性组6～63(中位数27)ms(P=0.001);RMS40:阳性组1.6～6.0(中位数7.6)μV,阴性组8.2～162.9(中位数27.7)μV(P=0.000)。结论心室晚电位在预测ARVD/C高危性可能有一定价值。Objectives To investigate the relationship between ventricular tachycardia(VT) and ventricular late potential(VLP) in patients with arrhythmogenic right ventricular dysplasia /cardiomyopathy(ARVD /C).Methods Patients with ARVD/C,aged(35±15) years,including 28 men and 10 women,were received signal-averaged electrocardiography to record total QRS duration(QRST),low potential terminal signals(LPS40),root mean square of the last 40 ms(RMS40) and 24 h-Holter monitoring for recording VT and premature ventricular ...
