检测老年慢性心力衰竭（CHF）患者的心率变异（HRV）时Ⅱ定量指标SDNN、SDANN 、RMSSD、三角指数，观察其与CHF病情的相关性及临床价值。方法分别选取80例老年CHF患者和50例无心衰老年受试者，测定HRV时Ⅱ指标，对两组间检测结果进行对比分析，并观察HRV与心功能NYHA分级的关系。结果观察组HRV时Ⅱ指标明显低于对照组（P<0.05），根据NYHA分级Ⅲ～Ⅳ级患者的各项时Ⅱ指标均显著低于Ⅰ～Ⅱ级患者（P<0.05）。结论 HRV的变化与老年CHF患者的心功能损害程度密切相关，监测心率变异的变化，对于老年CHF患者病情的评价及预后有积极意义。

Objective To detect heart rate variability (HRV) time quantitative index SDNN, SDANN, RMSSD, trian-gle index of elderly patients with chronic heart failure (CHF) and observe the clinical value and their correlation with the dis-ease activity of CHF. Methods Selected 80 cases of elderly patients with chronic heart failure and 50 elderly patients without heart failure, detected heart rate variability index. The test results analysis and investigated the relationship between HRV and NYHA cardiac function classification of the two group were compared. Results The HRV time domain indexes of the obser-vation group was significantly lower than that of the control group (P<0.05). NYHA Ⅲ~Ⅳ patients all the time domain index were significantly lower than those in grade Ⅰ~Ⅱpatients (P<0.05). Conclusion Heart function damage was closely related to the variations of HRV in elderly CHF patients, monitoring the change of heart rate variability had great significance for the e-valuation and prognosis of elderly patients with heart failure disease.
