冠状动脉病变范围与心率变异性的相关性研究

The Relationship between Coronary Lesions and Heart Rate Variability

本研究通过对69例CHD患者(完成冠状动脉造影)进行Gensini评分、分组,同时设正常对照组56例。全部进行24h动态心电图监测,并做时域指标和频域指标的HRV分析。结果显示CHD组HRV各项指标均低于对照组(P<0.05),不同冠状动脉病变范围和程度其时域指标及频域指标降低程度不同,各组对照具有显著性差异(P<0.01)。说明CHD患者HRV明显下降,与冠状动脉病变范围及程度呈正比。

69 cases of coronary heart disease completed angiography of coronary artery were selected and Gensini score, and 56 cases as normal control group. Subjects were monitored by 24--hour ambulatory electrocardiogram to obtain the parameters of HRV, including time domain and frequency domain. Compared the values of HRV in CHD groups with the control groups, results show significantly reduced（P〈0.01）. It shows positive correlation to the extent and degree of coronary lesions.
