摘　　要：目的了解冠心病(CHD)患者的心率变异性(HRV)特点,探讨CHD患者自主神经变化的临床意义。方法测定93例CHD患者和49例健康对照者24h心率变异性的时域指标,并进行比较分析。结果CHD组24hHRV指标水平明显低于健康对照组(P<0.01),差异有统计学意义。结论CHD患者HRV降低提示心血管自主神经系统功能受损害。Objective To understand the characterics of heart rate variability （HRV） in patients with coronary heart disease （CHD） and to study the clinical significance of autonomic nerve changes of CHD. Methods The time domain parameters of HRV were detected in 93 patients with coronary heart disease （CHD group） and 49 healthy controls （healthy control group）. The results were compared and analyzed （P〈0. 01）. Results The 24 h HRV level in CHD group was significantly lower than that in healthy control group （P〈0.01）. The difference was statistically significant. Conclusion Decreased level of HRV is an indicator of cardiovascular autonomic nervous system impairment in patients with CHD.
