摘　　要：目的:探讨老年冠心病患者心电图V1导联P波终末电势(PTFV1)与左室射血分数(LVEF)及冠脉造影结果的关系。方法:选择心内科住院的60岁以上患者119例,行冠脉造影检查明确诊断为冠心病的患者80例作为病例组,其余非冠心病患者39例作为对照组,分别对两组老年人进行超声心动图和心电图测试,并将所测冠脉狭窄程度与LVEF值、PTFV1负值进行相关分析。结果:冠状动脉狭窄组的PTFV1负值阳性率显著高于冠状动脉正常组(P<0.01),冠状动脉狭窄患者中PTFV1负值阴性组左室射血分数的显著高于PTFV1阳性组(P<0.01)。结论:老年冠心病患者PTFV1负值在一定程度上反映左心室受损的严重程度和冠状动脉病变的损害程度。Objective：To investigate the relationship between PTFV1 of electrocardiograph（ ECG） and left ventricular ejection fraction（ LVEF）and coronary angiogram（ CAG）in patients with coronary heart disease（ CHD）. Methods：A total of 119 patients aged 60 or above in cardiology department of Guizhou provincial peopleˊs hospital from April,2013 to October,2013 were enrolled in this study. A-mong them,80 patients diagnosed by coronary angiography examination as coronary heart disease （CHD）were defined as case group,and the remaining 39 cases of non coronary heart disease （ NCHD）were defined as control group. The echocardiography and ECG were examined in two groups and the correlation between coronary artery stenosis degree and LVEF value and PTFV1 negative value were analyzed. Results：The positive rate of PTFV1 negative value in case group was significantly high-er than that in control group（P﹤0. 01）. The LVEF value in the group of PTFV1 negative group was significantly higher than the PTFV1 positive group. Conclusion：The PTFV1 negative value of the eld-erly patients can,in a certain degree,reflect the extent of impairment of left ventricular sinister as well as the extent of damage in coronary artery disease.
