摘　　要：目的:分析心电图Pv_1终末电势(terminal force,Ptfv_1)评价冠心病早期心功能不全的诊断价值。方法:测定受检者心电图和心脏彩色多普勒;受检者冠心病组(120例)分成左室射血分数(LVEF)≥50％组(n=60),LVEF<50％组(n=60),另设正常对照组(n=60);对各组Ptfv_1进行分析.结累:以Ptfv_1≤-0.02 mm·s为异常标准,120例冠心病患者中Ptfv_1异常者96例,占80％。以Ptfv_1 ≤-0.04mm·s为异常标准,Ptfv_1异常者60例,占50％。冠心病患者中LVEF≥50％组与LVEF<50％组比较,分别以Ptfv_1≤-0.02 mm·s或≤-0.04 mm·s为异常标准,两组Ptfv_1异常均有非常显著差异(P<0.01)。结论:用Ptfv_1≤-0.02mm·s评价冠心病合并早期左心功能不全,其敏感性,特异性及真阳性率较高,且可观察心功能的动态变化,适合基层医院,有较高的临床实用价值。Objective: To explore the diagnostic value of terminal force (Ptfv1) of Pv1 in evaluating coronary heart disease (CHD) complicating left heart failure. Methods: The study cases were examined by electrocardiogram and cardiac color ultrasonic system. A total of 120 CHD patients were divided to left ventricular ejective fraction (LVEF) ≥50% group (60 cases) and LVEF≤50% group (60 cases). Control group contains 60 normal persons. Results: Taking Ptfv1≤-0. 02mm · s as abnormal standard, the morbidity in CHD group was 80% (96 cases), when taking Ptfv1≤0. 04mm ·s as abnormal standard, the morbidity was 50% (50 cases). Differences of CHD morbidity between LVEF ≥50% group and ≤50% group, taking Ptfv1≤ -0. 02mm · s or Ptfv1≤ -0. 04mm · s as abnormal standard, were significance (P<0. 01). Conclusion: The sensibility, speciality and true positive were higher when taking Ptfv1≤ - 0. 02mm · s as abnormal standard for evaluating CHD complicating left heart failure. It is suitable basal layer hospital.
