摘要

目的:检测原发性高血压及合并左室肥厚患者窦性心率震荡（Heart rate turbulence

HRT）情况

探讨患者自主神经状态。方法:原发性高血压89例

根据超声心动图结果分为左心室肥厚组45例

左心室正常组44例;健康对照组47例共3组。记录其24h动态心电图

计算窦性心率震荡初始值（Turbulence onset

TO）与震荡斜率值（Turbulenceslope

TS）

比较3组之间的差异。结果:左心室肥厚组、左心室正常组较对照组TO增大

TS降低

TO、TS异常发生率高（均P<0.01）;左心室肥厚组较左心室正常组TO增大

TS降低

TO、TS异常发生率高（均P<0.01）。结论:原发性高血压患者的HRT明显减弱

合并有左室肥厚的患者自主神经功能受损更加严重

提示高血压患者存在自主神经损害

左室肥厚者损害更加明显。

Abstract

Objective:To exam sinus heart rate turbulence in patients with essential hypertension(EH)and left ventricular hypertrophy (LVH)

and to analyzeautonomic nervous system of the patients.Methods:The study group consisted of 89 patients with EH.Based on echocardiogram

the hypertensives were divided into those with left ventricular hypertrophy(LVH)(n=45)and those without LVH (n=44).The control group is normotensive participants(n=47).In each subject

24 hours dynamic electrocardiogramwas recorded

Turbulence Onset(TO)and Turbulence Slope(TS)were calculated and the difference was compared.Results:The difference in TO in three group was statistically significant(P<0.01).TO was higher but TS was lawer in EH group with LVH and EH group without LVH

as compared with those in control group(P<0.01).The abnormal incidence rates of TO and TS were high(P<0.01).TO was higher

but TS was lawer in EH group with LVH than those in EH group without LVH(.P<0.01).The abnormal incidence rates of TO and TS were high(P<0.01).Conclusion:HRT of EH patients becomes significantly low

and the autonomic nerve function in EH patients with LVH is injured more seriously

This suggests that dysfunction of autonomic nervous system hasoccurred in patients with EH

and the autonomic nerve function in EH patients with LVH is injured more seriously.
