目的:分析冠心病和非冠心病病人室性早搏发生规律及机制。方法:选择109例住院患者,根据冠状动脉造影的结果分为冠心病组(53例)和非冠心病组(56例),依据动态心电图检查结果,做单位小时平均心率和室早发生百分率或千分率随24 h时间变化曲线,观察两曲线变化情况,并对两组进行对比分析。结果:非冠心病组两曲线多呈一致,且室早发生率峰值在第一个平均心率峰值出现的同时或其后;冠心病组两曲线多呈相反或无关,室早发生率峰值在第一个平均心率峰值之前(约夜间1⁷时)。结论:非冠心病病人室早发生可能与交感神经兴奋增强、迷走神经张力降低有关,冠心病病人室早发生恰与此相反。

Objective: To analyse the occurrence rate of ventricular premature beat between coronary heart disease(CHD) and non-CHD.Methods: We have collected 109 patients and divided them into CHD group(53 patients) and non-CHD group(56 patients) by coronary angiography.We maked the curve of two groups by the results of 24 hours ECG and compared these curves. Results: Two curves of non-CHD group were at the same trend but those of CHD group are not at the same trend.Most ventricular premature beat of CHD group occured at 1 to 7 AM.Conclusions: The occurrence of ventricular premature beat of non-CHD is related with more tensive sympathetic nerve and less tensive vagus,but which of CHD is reverse.
