摘　　要：目的:探讨心率变异性(HRV)和心率减速力(DC)在高血压合并冠心病患者中的相关性,为高血压合并冠心病的临床诊治提供参考。方法:选取81例高血压合并冠心病患者(研究组)和80例健康志愿者(对照组)为研究对象,分别监测DC和HRV。结果:结果表明高血压合并冠心病患者心率减速力明显低于正常组研究对象,P<0.05,差异有统计学意义;高血压合并冠心病患者心率变异性的SDNN、RMSSD和PNN50等三个指标均较低,均P<0.05,差异有统计学意义;高血压合并冠心病患者心率减速力与心率变异性的SDNN、RMSSD和PNN50等三个指标均呈正相关性,均P<0.05。结论:高血压合并冠心病患者DC与HRV具有正相关性,可协同作为诊治依据。Objective：To investigate the correlation of heart rate deceleration force （ DC） and heart rate variability （ HRV） in patients with hypertension combination with coronary heart disease .Method：81 cases of patients with hypertension combination with coronary heart disease （ study group ） and 80 healthy volun-teers （ control group ） were monitored by DC and HRV .Result：The results showed that the DC of the study group was significantly lower than that of the control group , P＆lt;0.05.The SDNN, RMSSD and PNN50 of the HRV of the study group were all significantly lower than those of the control group , all P＆lt;0.05.And there was positive correlation between the two groups of the SDNN , RMSSD and PNN50 of the HRV, all P＆lt;0.05. Conclusion：There＆#39;s positive correlation of DC and HRV for patients with hypertension combination with cor-onary heart disease and which could be used as treatment based on collaboration .
