【摘要】 目的　探讨运动疗法对老年陈旧性心肌梗死 (OMI)患者心率变异性 (HRV)的影响。方法　在运动疗法前和疗程结束后 ,应用 2 4h连续动态心电图监测老年OMI患者的HRV时域指标 ,并行心脏超声获取老年OMI患者EDV、ESV、EF、CO值且设对照组。结果　①试验组在运动疗法前 ,HRV和EDV、ESV、EF、CO值均低于对照组值 (P <0 .0 5 ) ;②试验组运动疗法后HRV和EDV、ESV、EF、CO值较对照组无明显差异(P >0 .0 5 ) ;③试验组运动疗法后HRV和EDV、EF、CO值较其运动疗法前明显增高 ,差异有非常显著性意义(P <0 .0 1)。结论　运动疗法利于改善老年OMI患者的心脏功能更多还原

【Abstract】 Objective To study the effects of exerci se on heart rate variability (HRV) in elderly patients with old myocardial infarct ion (OMI). Methods Fourty-three patients were recrui ted and divided into an exercise group (24 cases) and a control group (19 cases) . All the patients were given conventional treatment, with those in the exercise group being administered with adequate exercise in addition. Twenty-four hour Holter taper and ultrasonic cardiogram were performed before and at the end of t he 1 month exercise program, respectively, for HRV analysis and cardiac function assessment. Results Before the exercise,HRV and card iac function of senile patients with OMI were significantly lower than those of the controls( P <0.05);After the exercise,the HRV and cardiac function were improved significantly in the exercise group as compared with counterpart befo re treatment( P <0.01)but not significantly different from those of the cont rol group( P >0.05). Conclusion Exercise can sign ificantly improve the cardiac function of elderly patients with old myocardial i nfarction.更多还原
