Results: Heart rate(HR)in Carvedilol group were significantly lower than those in control group (P＜0.01). The LV ejection fraction (LVEF), stroke volume (SV) and E/A were significantly higher than those in control group (P＜0.01).
结果：治疗组较对照组心率(HR)明显降低（P＜0.01）， 每搏量（SV）﹑左室射血分数（LVEF）﹑E/A值明显提高（P＜0.01），改善左室收缩和舒张功能。
