海水浴体疗对老年2型糖尿病患者心率变异性的影响

目的：探讨海水浴体疗对老年2型糖尿病（T2DM）患者心脏自主神经功能的康复作用。方法：于海水浴前后对60例海水浴组和60例一般疗养组的T2DM患者进行24h动态心电图检测，并分析其心率变异性（HRV）时域指标，以心脏超声检测左室射血分数（LVEF），并与30例健康对照组的进行比较。结果：①疗养前：T2DM患者HRV和LVEF值均较健康组降低（P〈0.05～〈0.01），且T2DM合并无症状心肌缺血（DM＋SMI）组较单型性T2DM（DM）组的降低显著（P〈0.05～〈0.01）；②疗养后：与疗养前比海水浴DM组各值升高显著（P〈0．05），DM＋SMI组升高非常显著（P〈0.05～〈0.01）；而一般疗养组各值均无明显升高（P〉0．05）。结论：海水浴体疗对老年T2DM患者心脏自主神经功能有着积极康复作用。

Effect of sea water bath exercise on heart rate variability in aged patients with type 2 diabetes mellitus

Objective:To discuss the effect of sea water bath physical exercise on HRV in aged patients with type 2 diabetes mellitus(T2DM).Methods:HRV by 24-h Holter and left ventricular ejection fraction(LVEF) by ultrasound cardiogram were detected in 30 healthy aged persons,60 aged T2DM patients with routine convalesce method and 60 aged T2DM patients with sea water bath before and after sea water bath.Results:Before sea water bath,compared to healthy control group,the HRV and LVEF of aged patients with T2DM lowered remarkably (P<0.05~<0.01), of patients with T2DM and silent myocardial ischemia(DM SMI) decreased remarkably than those of patients with simple T2DM (SDM) (P<0.05~<0.01).After sea water bath the HRV and LVEF significantly increased in aged T2DM patients with sea water bath (P<0.05~<0.01).The above stated indexes of routine convalesce group were no difference(P>0.05) before and after sea water bath.Conclusion:Sea water bath physical exercise can improve HRV and LVEF;it can serve as a rehabilitation method for aged T2DM disease.
