摘　　要：目的分析探讨12导联同步动态心电图万次以上室性期前收缩的特征与意义。方法回顾性分析94例万次以上室性期前收缩患者按不同条件分类后的分布情况。结果 94例万次以上室性期前收缩患者中,①按病因分类:冠心病27例,心律失常17例,扩心病15例,高血压心脏病11例,肺心病8例,糖尿病5例,胸闷、心悸待查3例,心肌梗死、心肌炎、心绞痛各2例,脑梗死、胆结石各1例。②按Lown分级法分类:Ⅱ级31例、Ⅲ级21例、Ⅳ级A15例、Ⅳ级B26例、Ⅴ级1例。③按室性期前收缩发生的时间分类:白天发生率高者32例,夜间发生率高者34例,昼夜均发生者28例。④按室性期前收缩频率分类:4万～5万次∕d4例、3万～4万次∕d9例、2万～3万次∕d20例、1万～2万次∕d61例。结论 12导联同步动态心电图检出万次以上室性期前收缩,应首先查清引起室性期前收缩的原因,然后结合临床综合判断,才能正确地对其进行评价和预后的估评。Objective To analyze and discuss the characteristics and meaning of premature ventricular beats of more than 10 000 times with dynamic changes of 12 lead electrocardiograms.Methods Give a retrospective analysis of the general distribution of 94 cases of patients with premature ventricular beats of more than 10 000 times,who were Classify by different conditions. Results Among 94 cases of patients with premature ventricular beats of more than 10 000 times, ① classify by pathogeny:27 cases with coronary disease, 17 cases with arrhythmia cordis, 15 cases with dilated cardiomyopathy, 11 cases with hypertensive heart disease, 8 cases with pulmonary heart disease, 5 cases with diabetes, 3 cases with chest dejected and palpitate to be checked further, 2 cases with myocardial infarction, 2 cases with myocarditis, 2 cases with angina pectoris, one case with cerebral infarction and one case with cholelithiasis. ② Classify by Lown classification: 31 cases of level Ⅱ, 21 cases of level Ⅲ, 15 cases of level ⅣA, 26 cases of level ⅣB, and one case of levelⅤ. ③ Classify by time of the occurrence of premature ventricular beats: 32 cases mostly strike in the daytime; 34 cases mostly strike at night, and 28 cases strike by day and night. ④ Classify by the frequency of premature ventricular beats(times/day): 4 cases with 40 000-50 000 times /day,9 cases with 30 000-40 000 times/day,20 cases with 20 000-30 000 times/day,and 61 cases with 10 000-20 000 times/day. Conclusion To successfully detect premature ventricular beats over 10 000 times with 12 lead dynamic electrocardiograms, first we should dig out the cause of premature ventricular beats and then combine comprehensive clinical experience, so that we can make correct evaluation and prognostic evaluation of premature ventricular beats.
