摘要
心率震荡是反映自主神经功能状况的又一新的心电生理学检测方法,主要用于冠状动脉粥样硬化性心脏病、心力衰竭、糖尿病等预后的预测。有关其在高血压中的研究甚少,但已有的结果均证实高血压患者心率震荡现象明显减弱,尤其是伴左心室体积扩大、恶性室性期前收缩以及脉压增大的患者,提示高血压患者的自主神经功能明显受损,心率震荡可作为高血压患者预后不良的新指标。
Heart rate turbulence（HRT）is a new electrophysiological method to evaluate the function of autonomic nervous system.It is used extensively to predict the prognosis of coronary heart disease,heart failure and diabetes.Researches about predictive value of HRT for patients with hypertension are very few,but results have showed HRT parameters in hypertension were attenuated obviously,especially in patients with increased left ventricle mass,malignant ventricular premature beats,and greater pulse pressure.This phenomena suggested that the function of autonomic nerve was hurt severely in patients with hypertention.HRT can be considered as a new index of hypertention with poor prognosis.
