老年冠心病室性心律失常与心率变异临床探析

目的 分析老年冠心病室性心律失常与心率变异情况。方法 选取老年冠心病患者103例,将其做为观察组;选取同期非冠心病老年患者103例,将其做为对照组,2组患者均给予24 h动态心电监测,对比2组患者心率变异性指标。结果 观察组患者心率变异性指标检测值均低于对照组,差异具有统计学意义（P〈0.05）。观察组患者室性心律失常与心肌缺血的发生率显著高于对照组,差异具有统计学意义（P〈0.05）。观察组心功能分级Ⅱ级或Ⅱ级以上患者心率变异指标检测值显著低于0-Ⅰ级患者,差异具有统计学意义（P〈0.05）。结论 将心率变异检测指标应用于老年冠心病患者检查中,能够更好预警出老年冠心病猝死的高危人群,对指导患者治疗及临床用药均有重要意义。

Objective To analyze the elderly coronary heart disease （CHD） of ventricular arrhythmias and heart rate variation. Methods To select 103 cases of senile coronary heart disease patients admitted in September, it as observation group; selected in the same period of 103 cases of elderly patients with coronary heart disease, to be as a control group, two groups of patients were given 24-hour holter monitor, compared two groups of patients with heart rate variability index. Results The observation group of patients with heart rate variability index values are lower than the control group, difference has statistical significance （P〈0.05）. Observation group the incidence of ventricular arrhythmia and myocardial ischemia in patients with significantly higher than that of control group, difference has statistical significance （P〈0.05）. Observation group heart function class 1] or 11 heart rate variability index readings above level was significantly lower than 0- I patient groups, statistically significant difference （P〈0.05）. Conclusion Will detect heart rate variation index used in elderly patients with coronary heart disease, to better warning of senile coronary heart disease （CHD） people at high risk of sudden death, to guide patient treatment and clinical medicine has important significance.
