患者女、85岁,因间歇性心悸、胸闷、心动过速就诊。临床诊断:冠心病、阵发性心动过速。心电图示(见图):窦性心律,心率58bpm,P-R间期0.11s,QRS时限0.16s各导联QRS起始部均粗钝呈δ波,V1~V6导联δ波与QRS主波均向上,考虑为A型心室预激。V1~V3呈宽大R波,I、II、av F、V5、V6导联终末S波及AVR之R波粗钝>0.04s,P-J间期为0.30s(>0.27s),提示:A型心室预激合并完全性右束支传导阻滞。其胸导ST-T改变属于A型心室预激及完
Female patient, 85 years old, due to intermittent palpitations, chest tightness, tachycardia treatment. Clinical diagnosis: coronary heart disease, paroxysmal tachycardia. Electrocardiogram (see picture): Sinus rhythm, heart rate 58bpm, PR interval 0.11s, QRS duration 0.16s Each lead QRS beginning were dull δ wave, V1 ~ V6 lead δ wave and QRS main wave mean Up, consider A-type ventricular pre-excitation. V1 ~ V3 were large R wave, R waves of terminal wave S and AVR of I, II, av F, V5 and V6 were blurs> 0.04s and PJ was 0.30s (> 0.27s), suggesting that type A Ventricular pre-excitation combined with complete right bundle branch block. The chest guide ST-T changes belong to type A ventricular pre-excitation and finish
