以往认为.Ptf—V_1(V_1P的终末电势)异常反映左房负荷过重,即在左房压力或容量负荷过重时,Ptf—V_1出现异常。近年来发现,在右心病变时,Ptf—V_1也出现异常。为了明确肺心病与异常PtJ—V_1的关系,特将我院肺心病人心电图出现的Ptf—V_1情况加以总结,并对其机理进行探讨: 科材和方法我院1988～1991年内科住院老年肺心病患者87例,其中,男55例,女32例,年龄6～83岁,诊断符合1977年全国第二次肺心病会议的标准,并除外瓣膜病。高血压病。高
In the past, Ptf-V_1 (terminal potential of V_1P) abnormally reflected left atrium overload, that is, abnormal Ptf-V_1 occurred when left atrial pressure or volume overload. In recent years, it has been found that Ptf-V_1 is also abnormal in right heart lesions. In order to clarify the relationship between pulmonary heart disease and abnormal PtJ-V_1, especially the electrocardiogram of our hospital pulmonary heart disease Ptf-V_1 situation is summarized, and its mechanism is discussed: Materials and methods Our hospital from 1988 to 1991 inpatient senile lung 87 patients with heart disease, of which 55 were male and 32 females, aged 6 to 83 years old, the diagnosis consistent with the standard of the Second National Conference on Cor Pulmonary Disease in 1977, with the exception of valvular disease. High blood pressure. high
