摘  要:目的:为探讨Ptfv1对诊断慢性肺心病右房肥大和右心功能不全的临床价值,方法:对126例肺心病患者及104例正常人的常规心电图P波进行分析,并对Ptfv1异常者进行动态心电监测。对其中70例患者进行了超声心动图检查。结果:肺心病加重期Ptfv1阳性率38.88%,缓解期转阴率36.72%,改善率40.81%,总好转率77.53%。两期比较差异有高度显著性(P<0.001)。肺型P波阳性率46.3%,与Ptfv1比较差异无显著意义(P>0.05)。正常人对照组未发现Ptfv1阳性及肺型P波。超声心动图显示右房内径增大率为71.43%,其中Ptfv1阳性78%,肺型P波88%。结论:提示肺型P波和Ptfv1异常的临床符合率较高,两者在诊断价值上可能是一致的,提示Ptfv1<-0.02mm·s可作为判定慢性肺心病右房肥大的诊断标准之一。Ptfv1值随右心功能状态变化而变化,故Ptfv1值动态变化可作为右心功能不全的诊断指标之一。Objective:To discuss the clinical value of Ptfv1 in diagnosing right atrial hypertrophy and right heart failure in chronic pulmonary heart disease.Methods:Routine electrocardiograms (ECG) of 126 pulmonary heart disease patients and 104 normal adults were analysed and of which abnormal Ptfv1 was dynamically monitored:Doppler examinations were performed on 70 cases of the studied patients.Results:In the progressive stage of pulmonary heart disease. The positive rate of Ptfv1 was 38.88%;and in the recovering stage the negative reversing rate was 36.72%;The improving rate was 40.81%.The total improving rate was 77.48%.There was significant difference between the two stages (P<0.001) .The positive rate of pulmonary p-wave was 46.3%.and was no significant difference from Ptfv1 positive rate (P>0.05) .There were no positive Ptfv1 and pulmonary p-wave in the normal control group.The rate of enlarged right atrium detected by doppler was 71.43%.of which positive Ptfv1 rate was 78% and the rate of pulmonary pware was 88%.Conclusions:Ptfv1 abnormalities correspond with pulmonary pwave in high propotion and it is considered that they are of the same diagnostic value.It is also indicated that Ptfv1 <-0.02mm.s could be one of the diagnostic standards for right atrival hypertrophy in pulmonary heart disease.Ptfv1 changes in pulmonary heary disease ptfVl changes with right heart function.so dynamic changes of Ptfv1 could be one of the diagnostic datae for right heart function.
