冠状动脉搭桥术前后心电图变化探究【摘要】 目的 研究冠状动脉搭桥术前后心电图改变。方法 对24例冠脉病变患者在入院做冠状动脉搭桥术前、术后第1周、2~4周及1个月后各记录常规12导联或18导联心电图。结果 与术前比较,术后第1周窦速、早搏、异常Q波、多导联ST段抬高均较前明显增多, ST T改变较前明显, 2周以后上述改变显著减少或消失。结论 冠状动脉搭桥患者由于手术创伤、再灌注损伤等原因致使术后早期出现上述心电图变化,此后逐渐减少至术前水平或消失。 【关键词】冠状动脉搭桥术;心电图;改变 Coronary artery bypass surgery and electrocardiogram changes CHI Lian hua,HUANG Lu,LIU Zhi lan.The First People’s Hospital ofZhaoqing,Zhaoqing,Guangdong 506021,China 【Abstract】 Objective To research of coronary artery bypass surgery and electrocardiogram changes.Methods 24 cases of coronary artery disease in patients with three lesions were doing coronary artery bypass preoperative and postoperative first 1 week,2~4 week and 1 months after each record regular 12 lead or 18 lead electrocardiogram.Results Compared with the preoperative and postoperative first 1 W sinus,premature beat,abnormal Q wave,lead st elevation are significantly increased,ST T changed significant;after2 week the change significantly reduce or disappear.Conclusion Coronary artery patients with surgical trauma,and pitched reperfusion injury early postoperative reasons causing the electrocardiogram,then change to the preoperative level gradually decrease or disapper. 【Key words】 Coronary artery bypass surgery; Electrocardiogram; Change 冠状动脉旁路移植术,俗称冠状动脉搭桥术,是一门通过外科手术治疗冠心病的技术。从它问世至今,因其疗效确切,一直是冠心病治疗中主要和基本手段之一。现主要是对冠状动脉搭桥术前后心电图变化进行对比分析。 1 资料与方法 1.1 研究对象 2001年8月至2008年11月在本院经冠状动脉造影术确诊为冠脉病变(绝大部分为三支血管病变)的患者24例,男20例,女4例,年龄48~78岁,平均61岁。 1.2 研究方法 采用日本光电6511型心电图机或北京美高仪公司研制的ECG LAB 2.0心电工作站对确诊为冠脉病变患者入院术前、术后第1、2~4周及1个月后进行常规12导联或18导联心电图描记心电图,走纸速度25 mm/s ,电压10 mm/mV。 1.3 冠状动脉搭桥术的适应证[1] ①明显的左主干病变(狭窄程度75%)或相当于左主干病变的左前降支和回旋支近端狭窄≥70%;②3支血管病变或者2支血管病变伴左前降支近端狭窄,尤其是左心室功能不正常(EF 1
