为了解心脏右室的全貌及电学变化规律,用日本6151型心电图机描记50例健康人全部右胸导联(V_1、V_3R～V_9R)心电图.结果:距心脏右室近的导联,R波振幅均值大,反之,均值小.S波振幅均值自V_1、V_3R～V_9R依次减小.正常人出现的Q>0.04秒>R/4,S—T段抬高>0.05毫伏,难与发病的右室梗死鉴别.上述结果表明:全右胸导联心电图不能客观反映心脏右室的全貌,故亟应寻找新导联、新方法,全方位观察心脏. In order to understand the whole picture of the right ventricle and the electrical changes, ECG of all the right chest leads (V_1, V_3R ~ V_9R) in 50 healthy people were recorded by 6151 electrocardiogram in Japan.Results: Amplitude mean value is large, on the contrary, the mean value is small.The average value of S wave amplitude decreases from V_1, V_3R ~ V_9R in turn.Q> 0.04s> R / 4, S-T elevation> 0.05mV in normal subjects, Of the right ventricular infarction.The above results show that: the right chest lead ECG can not objectively reflect the whole picture of the right ventricle, it is urgently to find new leads, new methods, all-round observation of the heart.
