本文报告6例住院监护右室梗塞患者的临床资料以及一例尸解资料,对照分析了心电图表现。作者等认为急性下壁梗塞时,加做右胸导联V_3R、V_4R、V_5R,可提高右室梗塞的检出率。如发现V_1为rS型时,而V_3R、V_4R、V_5R呈Qr或QS型、Q波>0.03s、Q/R比值≥1/3;ST段抬高≥0.5mm有合并右室梗塞的可能。再加做右胸心电图标测可估计右室梗塞的范围,同时藉自身对照可观察病情的演变,有助于判断预后,评定疗效。此法具有简便、有效、可靠的优点。
This article reports 6 cases of hospitalized patients with right ventricular infarction clinical data and a case of autopsy data, the control analysis of ECG performance. The authors believe that acute inferior wall infarction, plus the right chest lead V_3R, V_4R, V_5R, can increase the detection rate of right ventricular infarction. If found V_1 rS type, and V_3R, V_4R, V_5R were Qr or QS type, Q wave> 0.03s, Q / R ratio ≥ 1/3; ST elevation ≥ 0.5mm with the possibility of right ventricular infarction. Coupled with the right chest ECG can be measured to determine the scope of right ventricular infarction, while the control by their own observation of the evolution of the disease can help determine the prognosis, assess the efficacy. This method has the advantages of simple, effective and reliable.
