高血压患者心率变异性与血压变异性分析

目的 分析高血压患者心率变异性与血压变异性的关系.方法 对高血压患者120例按1999年WHO/ISH高血压诊断标准分为:1级高血压40例,2级高血压40例,3级高血压40例,另设正常血压对照组40例,均同时检测心率变异性与血压变异性.结果 各组间心率变异性差异有统计学意义(P<0.05或P<0.01),随组间血压增高,心率变异性趋向减少;各组间血压变异性差异有统计学意义(P<0.01),随组间血压增高,血压变异性趋向增大.结论 高血压患者血压分级与心率变异性和血压变异性有一定关系.

Study of the heart rate variability and blood pressure variability in hypertension grading

Objective To study the heart rate variability(HRV) and blood pressure variability(BPV) in patients with different grades of hypertension.Methods 120 cases of patients with hypertension,according to 1999 WHO/ISH hypertension diagnostic criteria are:1 hypertension in 40 cases,2 of hypertension in 40 cases,3 of hypertension in 40 cases and 40 cases of normal control group were detected heart rate variability and blood pressure variability.Results HRV was significantly different between the two groups(P <0.05 or p <0.01).The blood pressure increased and HRV tended to decrease.The BPV was significantly different(P < 0.01) between the two groups;the blood pressure increased and the BPV tended to increase.Conclusion The grade of hypertension is related to HRV and BPV.
