One hundred consecutive patients scheduled for coronary artery bypass grafting were randomized to receive either blood or crystalloid cardioplegia. Successful Holter monitoring for rhythm disturbances was done before and immediately after the operation in 83 cases. With both modes of cardioplegia there were increases in the occurrence of rhythm disturbances postoperatively. The increases were mostly statistically significant. There was no intergroup differences in the occurrence of arrhythmias. The association between these disturbances and cross-clamp times, myocardial temperatures during cross-clamping, myocardial fibrillation times during and after cross-clamping, CK-MB values and perioperative infarction all indicated ischaemia or incomplete myocardial protection as a major cause of the immediate postoperative rhythm disturbances.
100例计划接受冠状动脉搭桥术的连续患者被随机分为接受血液停搏液或晶体停搏液两组。83例患者在手术前和手术后立即成功进行了动态心电图监测以检测心律失常。两种停搏液模式下,术后心律失常的发生率均有所增加。这些增加大多具有统计学意义。心律失常的发生率在组间没有差异。这些心律失常与阻断时间、阻断期间心肌温度、阻断期间及之后的心肌颤动时间、肌酸激酶同工酶(CK-MB)值和围手术期梗死之间的关联均表明,缺血或心肌保护不充分是术后即刻心律失常的主要原因。
