摘要
目的探讨常规12导联心电图指标对静息状态下冠状动脉病变的预测价值。方法回顾性分析1998年3月~2006年1月拟诊不稳定型心绞痛并行冠状动脉造影患者(104例)的造影资料及冠脉造影前心电图。以左主干、前降支、回旋支、右冠状动脉中任一支狭窄≥50%者为阳性,将患者分为阴性组(8例)、单支病变组(41例)、双支病变组(25例)、三支病变组(16例)、左主干病变组(14例,可合并单支、双支或三支病变)。各组病例的年龄、性别、化验检查等指标进行统计学分析;计数各组病例心电图aVR导联ST段抬高病例数、异常导联数、ST段移位绝对值之和、异常导联数+ST段移位绝对值之和、ST段时间,在单支病变组、双支病变组、三支病变组和左主干组之间进行统计学分析。结果①年龄:单支病变组与左主干病变组比较有显著性差异(P<0.05),其它各组间比较无显著性差异(p>0.05)。②aVR导联ST段抬高、异常导联数、ST移位、异常导联+ST段移位:单支病变组与三支病变组、左主干病变组之间比较有显著性差异(p<0.05);ST段改变时间:单支病变组与左主干病变组之间比较有显著性差异(p<0.05),但与三支病变组比较无显著性差异(p>0.05)。③aVR导联抬高、ST段移位、异常导联+ST段移位:双支病变组与三支病变组、左主干组比较有显著性差异(p<0.05);异常导联,双支病变组与三支病变组、左主干病变组比较无显著性差异(p>0.05);ST段时间:双支病变组与左主干病变组比较有显著性差异(p<0.05),而与三支病变组比较无显著性差异(p>0.05)。结论aVR导联抬高、ST段移位、异常导联+ST段移位是识别单支病变或双支病变与三支病变或左主干病变的敏感指标;ST段时间是识别单支病变或双支病变与左主干病变的敏感指标,但对识别三支病变不敏感;异常导联数对识别单支病变与三支病变或左主干病变敏感,但对识别双支�
Objective To find the relationship between the 12-lead resting electrocardiographic features and coronary artery pathological changes, and evaluate the value of predicting coronary artery pathological changes by 12-lead resting ECG. Methods ECG and coronary angiography (CAG) of 104 patients (1998.3- 2006.1) were observed and analyzed. All patients were divided into several groups: Negative group (NG, 8patients), 1-vessel disease group (1VDG, 41 patients), 2-vessel disease group (2VDG, 25patients), 3-vessel disease group (3VDG, 16 patients, LAD+LCX+RCA), left main artery disease group (LMDG, 14 patients). We analyzed the general characters, the amount of ST-segment deviation, ST-segment elevation in lead aVR, the number of leads with abnormal ST segment, the amount of ST-segment deviation+the number of leads with abnormal ST segment, ST segment time among 1VDG, 2VDG, 3VDG and LMDG. Results 1. Age: There is significant difference between 1VDG and LMDG (p〈0.05),There are not significant differences among other groups (p〉0.05). 2. There are significant differences between 1 VDG and 3 VDG (p〈0.05), also 3 VDG vs LMDG (p〈0.05) for ST-segment elevation in lead aVR, the amount of ST-segment deviation, the number of leads with abnormal ST segment, the amount of ST-segment deviation+the number of leads with abnormal ST segment. 1VDG vs LMDG (p〈0.05),There is significant differenc between 1 VDG and LMDG (p〈0.05)for ST segraent time item, but no significant difference between 1 VDG and 3 VDG (p 〉0.05). 3.There are significant differences between 2 VDG and 3 VDG (p〈0.05), also 2VDG vs LMDG (p〈0.05) for the ST-segment elevation in lead aVR, the amount of ST-segment deviation, the amount of ST-segment deviation+the number of leads with abnormal ST segment. There are no significant differences among 2 VDG, 3 VDG and LMDG (p 〉0.05) for the number of leads with abnormal ST segment. There is significant difference between 2 VDG and
