We studied forty-six cases, who had undergone coronary artery bypass grafting with retrograde cold blood cardioplegia for myocardial protection, to manifest the frequency and causative factors of postoperative conduction disturbances. We obtained the following conclusions. 1) Postoperative conduction disturbances developed in nineteen cases (41.3%), all of which were right bundle branch blocks, but these were usually transient and were not associated with further complications in the follow-up period. 2) There were no significant differences in many factors, including number of grafts, aortic cross-clamp times, or peak CK-MB between cases with and without postoperative conduction disturbances.
我们研究了46例接受冠状动脉搭桥术并采用逆行冷血心脏停搏液进行心肌保护的患者，以明确术后传导障碍的发生率及相关因素。我们得出了以下结论。1）19例（41.3%）患者出现了术后传导障碍，均为右束支传导阻滞，但这些通常是短暂的，且在随访期间未出现进一步并发症。2）在移植血管数量、主动脉阻断时间或CK-MB峰值等诸多因素方面，术后出现传导障碍和未出现传导障碍的患者之间无显著差异。
