本例图A窦性P-P间期规则,频率76次/min,R-R间期规则,P波与QRS波群无关,心房率大于心室率。其中R_5~R_7QRS波群呈室上性且形态一致,为房室交界性逸搏心律。图B中R_1~R_6 QRS波群宽大畸形,P-R间期不固定,多数QRS波群后可见P~-波,R-P~-间期0.15s,P~-波后可见代偿间歇(民后呈完全代偿间歇),为室性逸搏心律伴室房1:1逆传。图A R_1~R_4 QRS形
Figure A sinus P-P interval rules, the frequency of 76 beats / min, R-R interval rules, P-wave and QRS complex has nothing to do, the atrial rate greater than the ventricular rate. Among them, the R_5 ~ R_7QRS group was supraventricular and consistent in shape, which was the atrioventricular rhythm of atrioventricular junction. In Fig. B, the R_1 ~ R_6 QRS complex was abnormally large and the PR interval was not fixed. The P ~ - wave and RP ~ - interval were 0.15s after the QRS complex and compensatory intermittent after the P ~ - wave Complete compensatory intermittent), room for escape rhythm with room 1: 1 reverse.
