本文通过V_1导联P波末端部分(PTF-V_1)对急性肺水肿、急性心肌梗塞患者的临床观察,进行对比分析,以探讨PTF-V_1对判断左心功能不全的价值。临床资料正常对照组50例(男30例,女20例),年龄35～55岁,均无心血管病史,体检、血压、心电图、胸透等检查均正常。急性肺水肿组17例(男12例,女5例),年龄17～70岁,既往有高血压病、冠心病或心瓣膜、心肌疾病等病史,临床表现有典型肺水肿
In this paper, through the V_1 lead P wave end part (PTF-V_1) in patients with acute pulmonary edema and acute myocardial infarction clinical observation, comparative analysis to explore PTF-V_1 to determine the value of left ventricular dysfunction. Clinical data 50 cases of normal control group (30 males and 20 females), aged 35 to 55 years old, no history of cardiovascular disease, physical examination, blood pressure, electrocardiogram, chest X-ray examination were normal. Acute pulmonary edema in 17 cases (12 males and 5 females), aged 17 to 70 years old, with previous history of hypertension, coronary heart disease or heart valve disease, myocardial disease, the clinical manifestations of typical pulmonary edema
