自1964年 Morris 氏提出异常 Ptfv_1的诊断意义以来,深受临床工作者重视。我们在复习55例临床诊断心衰住院病例的基础上说明心衰与异常 Ptfv_1的关系,并做如下分析.资料与方法全组55例(男30例,女25例)系1988年1月～1989年4月经临床诊断心衰的内科住院患者.年龄35～67岁.平均52.4岁.55例中有41例 Ptfv_1异常(≤-0.03 mm·s),占74.55%(41/55)。病因及临床表现见表1.表1 41例心衰患者的临床表现Ptfv_1的测量方法:心电图 V_1导联上连续测得5个 P 波终末负性波的振幅(mm)和时间(s),以其乘积表示,正常时很少小于-0.03 mm.s Since 1964, Morris put forward the significance of the diagnosis of abnormal Ptfv_1, it has received great attention from clinicians. We reviewed 55 cases of clinical diagnosis of heart failure on the basis of the case of heart failure and abnormal Ptfv_1’s relationship and make the following analysis.Materials and Methods 55 cases of the whole group (30 males and 25 females) Department of January 1988 ~ Clinical inpatients with clinical diagnosis of heart failure in April 1989 were aged 35 to 67 years old with an average of 52.4 years old, of which 41 cases had abnormal Ptfv_1 (≤-0.03 mm · s), accounting for 74.55% (41/55). Etiology and clinical manifestations are shown in Table 1. Table 1 41 cases of clinical manifestations of heart failure Ptfv_1 measurement method: ECG V_1 lead continuously measured five P-wave negative terminal amplitude (mm) and time (s) , Expressed by its product, is normally less than -0.03 mm.s
