摘要
作者用24h动态心电图研究66例冠心病患者室性心律失常和心率变异的相关性。结果发现,高危室早(Lown分级≥Ⅲ级)的发生与性别、年龄、冠脉病变程度和心肌梗死与否无明显相关,但高危室早者的SDNN(P<0.01),SDANN(P<0.01)和LF(P<0.05)低于低危室早者(Lown分级≤Ⅱ级)。提示SDNN,SDANN和LF减小是高危室早发生的独立危险因子。
The relation between ventricular arrhythmia and heart rate variability was studied from 24 hour Holter recordings in sixty six patients with coronary heart disease. It was shown that high risk ventricular arrhythmia (VE) was not related to age, sex, impairment degree of coronary artery, myocardial infarction,but to heart rate variability:SDNN,SDANN and LF were lower in patients with high risk VE than those in patients with low risk VE. It is suggested that heart rate variability is an independent risk factor of ventricular arrhythmia.
