目的观察稳心颗粒对慢性心力衰竭患者心率变异性和QT离散度的影响。方法 80例慢性充血性心力衰竭患者随机随机分为2组,对照组为常规治疗,治疗组在常规治疗基础上加服稳心颗粒。分别观察治疗前后心率变异性和QT离散度的变化。结果 2个月后,治疗组心率变异性改善、QT离散度下降(P<0.01)。对照组均无明显变化(P>0.05)。结论稳心颗粒能够改善慢性心力衰竭患者心率变异性并能降低其QT离散度。
Objective To observe the effect of Wenxinkeli on heart rate variability and QT dispersion in patients with chronic heart failure. Methods Eighty patients with chronic congestive heart failure were randomly divided into two groups. The control group was treated routinely. The treatment group was given Wenxin granules on the basis of routine treatment. Changes of heart rate variability and QT dispersion before and after treatment were observed. Results After 2 months, the heart rate variability of the treatment group improved and the QT dispersion decreased (P <0.01). The control group had no significant change (P> 0.05). Conclusion Wenxin Granules can improve heart rate variability and reduce QT dispersion in patients with chronic heart failure.
