目的探讨冠心病患者心率变异性变化及临床意义。方法冠心病组102例,对照组(无冠心病的健康人80例),通过动态心电图检查分别测定时域指标(SDNN、SDANN、RMSSD、PNN50)和频域指标(TP、LF、HF),进行心率变异性变化的参数分析。结果冠心病组的指标SDNN、RMSSD、PNN50、TP、LF、HF均明显的低于健康组,p<0.01,有统计学意义。结论冠心病患者的心率变异性时域和频域指标均明显减低,反应自主神经调节心脏平衡的功能减低,易发生严重的心血管事件。
Objective To investigate the changes of heart rate variability in patients with coronary heart disease and its clinical significance. Methods 102 cases of CHD group and 80 cases of healthy control group without CHD were enrolled in this study. Time domain (SDNN, SDANN, RMSSD, PNN50) and frequency domain (TP, LF, HF) Parametric analysis of changes in heart rate variability. Results The indexes of SDNN, RMSSD, PNN50, TP, LF and HF in CHD group were significantly lower than those in healthy group (p <0.01), with statistical significance. Conclusion Heart rate variability in patients with coronary heart disease in both time domain and frequency domain indicators were significantly reduced response to autonomic nervous function to reduce the balance of the heart, prone to serious cardiovascular events.
