| 摘 要： | 目的探讨原发性高血压（EH）患者的心脏变时性（CR）和心率变异性（HRV）的关系。方法 EH患者50例,健康对照组30例,行运动平板及24h动态心电图检查,比较2组之间CR和HRV的差别,并分析之间的相关性。结果 EH组高血压组峰值心率、变时性指数、SDNN、PNN50显著低于对照组,LF/HF显著高于对照组,差异有统计学意义（p〈0.05）;峰值心率及变时性指数与SDNN、PN50显著正相关,与LF/HF显著负相关,差异有统计学意义（p〈0.05）。结论 EH患者有显著的CR及HRV的异常,表明EH患者存在心脏自主神经的损害;CR与HRV存在良好相关性。

| Abstract: | Objective To investigate the change of chronontropic action and heart rate variability(HRV)in patients with essential hypertension(EH).Methods Patients with EH and controls referred to perform treadmill exercise test and Dynamic Electrocardiogram(DCG).Heart rate,SDNN,PNN50 were recorded and analyzed.Chronotropic response index(CRI)were calculated and compared.Results The maximum increment of heart rate after exercise,chronotropic response index,SDNN,PNN50 were lower in Patients with EH than controls(p <0.05... |
