不停跳冠状动脉搭桥术后心律失常36例分析

Risk factors of arrhythmia happened after coronary artery bypass grafting

探讨不停跳冠状动脉搭桥术后早期心律失常的危险因素。将232例不停跳冠状动脉搭桥术后患者进行24h心电图监测并记录，分组依据为是否出现心律失常：一组为心律失常组（组1），一组为非心律失常组（组2）。分析心律失常与患者年龄、术前射血分数、搭桥支数与病变支数、心功能及合并症之间的关系。结果显示：心律失常的发生例数为36例，发生率为15．52％。心律失常组的高龄、射血分数低、心功能差的患者所占比例明显高于非心律失常组。结论：高龄、射血分数低、心功能差是心律失常发生的危险因素。

Objictive The purpose of this study is to approach the risk factors ofarrhythmia happened after off-pump coronary artery bypass grafting（OPCABG）. Methods： 232 patients undergone off-pump coronary artery bypass grafting weregiven 24 hour electrocardiogram monitoring and record them. 232 patients were divided two groups： arrhythmia group（groupl）and no-arrhythmia group （group2）according to electrocardiogram. To analyse the relation between arrhythmias and age, the ejection fraction,the number of bridge and vessels diseased, heart function, complication. Results： 36 cases happened arrhythmia post-operation. Incidence ratewas 15.52 %. The proportion of old age, the ejection fraction, poor heart function was manif higher in groupl than those in group 2. Conclusion： Old age the ejection fraction and poor heart function were risk factors of arrhythmia post-OPCABG
