The incidence of postoperative arrhythmia was 35.2% in 264 cases with complex congenital heart diseases underwent open heart surgery between Feb, 1988 and Aug, 1989. Postoperative arrhythmia was closely related to preoperative hematocrit, cardiomegaly, prolonged aortic occlusion, ratio of RV/LV systolic pressure greater than 0.75, hypokalemia and low cardiac output syndrome. Infusion of colloid solution and both potassium and magnesium as well as successful surgery and the preventive administration of antiarrhythmic agent played an important role in the prevention and treatment of postoperative arrhythmia.
1988年2月至1989年8月期间，264例接受心脏直视手术的复杂先天性心脏病患者术后心律失常的发生率为35.2%。术后心律失常与术前血细胞比容、心脏扩大、主动脉阻断时间延长、右心室与左心室收缩压比值大于0.75、低钾血症及低心排血量综合征密切相关。输注胶体溶液、钾和镁，以及成功的手术和预防性使用抗心律失常药物在术后心律失常的防治中起重要作用。
