思考心电图之3基本心律为窦性,PII直立,PavR倒置,P-P基本匀齐,频率约93次/分。基本心律之QRS波群时限为0.11”-0.12”,且SI、RavR增宽,呈右束支阻滞图形。I导联R_2、5提前出现,其形态与室上型QRS波群有异,时限为0.12”;其前有无关窦性P波,联律间期相等,考虑为交界性早搏伴室内差异传导(有长短规律,符合Ashman氏现象)。P_4和P_8无后继QRS波群,酷似II°房室传导阻滞,但根据以下理由应
The basic electrocardiogram of 3 basic rhythm thinking sinus, PII upright, PavR inversion, P-P is basically uniform, the frequency of about 93 beats / min. QRS complex of the basic rhythm of the time limit of 0.11 “-0.12”, and SI, RavR widening, right bundle branch block pattern. Lead I R_2, 5 appeared in advance, and its morphology and supraventricular QRS complex is different, the time limit is 0.12 "; before it has no relevant sinus P wave, associated law interval equal to consider borderline premature beats with differential indoor conduction (With the length of the law, in line with Ashman’s phenomenon.) P_4 and P_8 no subsequent QRS complex, resembles II ° atrioventricular block, but for the following reasons
