本文旨在通过对230例不同年龄和性别的正常人右胸导联各波形态的观察,以及对4例临床诊断为右室梗塞患者的分析,以提高心电图对右室梗塞诊断水平。一.230例正常人右胸导联心电图 1.P波形态:V_3R～V_6R的P波多数为直立,次为双向,少数倒置,个别平坦。P波振幅均≤1mm。 2.QRS形态:V_3R～V_6R大多呈rS型,次为rs(?)型、qr型。但呈rS型时,原则上为SV_3R>SV_4R>SV_5R>SV_6R。右胸前导联QRS振幅在5～10mm之间。
This paper aims to improve the diagnostic accuracy of ECG on right ventricular infarction by observing the wave patterns of right chest lead of 230 normal subjects of different ages and genders and analyzing 4 cases of patients with right ventricular infarction. 2.30 normal right chest lead ECG 1.P wave morphology: V_3R ~ V_6R P wave most of the upright, times for the two-way, a few inverted, individual flat. P wave amplitude are ≤ 1mm. 2.QRS morphology: V_3R ~ V_6R mostly rS type, followed by rs (?) Type, qr type. However, when the rS type, in principle, SV_3R> SV_4R> SV_5R> SV_6R. Right chest lead QRS amplitude between 5 ~ 10mm.
