72例冠心病患者冠状动脉病变范围与心率变异性的关系

目的:探讨冠心病(CHD)患者冠状动脉不同病变程度与心率变异性(HRV)的关系。方法:采用24h动态心电图监测,对72例CHD患者和60例正常人进行HRV时域分析和频域分析。结果:CHD组HRV各项指标均低于对照组(P<0.05),且不同冠脉病变范围和程度HRV具有显著性差异(P<0.01)。结论:CHD患者HRV明显下降,与冠脉病变范围和程度呈正相关。

Teh relationship between coronary lesions and heart rate variability

Objective: To study relationship between different coronary lesions and heart rate variability(HRV) in coronary heart diease (CHD) patients. Methods:72 patients with CHD and 60 healthy subjects were monitored by 24-hour ambulatory electrocardiogram to obtain the parameters of HRV, including time domain and frequency domain. Results: Compared with the control groups, the values of HRV significcmtly reduced in CHD patients(P<0.05);there were statistical differences between different vessel disease groups and narrowing disease groups(P<0.01). Conclusion: The values of HRV decreases obviously in CHD patients and it shows positive correlation to the extent and degree of coronary lesions.
