患者男性,63岁,临床诊断为冠心病、病窦综合征入院。附图为入院后24h动态心电图模拟V_1(M_v_1)导联的连续记录示:P-R间期为1.32—2.10s,P_2-R、P_5-R、P_7-R、P_9-R、P_(11)-R、P_(13)-R、P_(15)-R均0.27s,为基本的P-R间期,存在I°A-VB。P_1-R=0.72s,P_3-R=0.46s,P_4-R=0.76s,P_6-R=0.86s,P_8-R=0.81s,P_(10)-R=0.77s,P_(12)-R=0.84s,P_(14)-R=0.84s,为逸搏夺获之P-R间期,其P-R甚长,且R′-P与P-R呈负反馈关系。
Male patient, 63 years old, clinical diagnosis of coronary heart disease, sick sinus syndrome admission. The following figure shows the continuous recording of V 1 (M_v_1) lead of Holter in 24 hours after admission: PR interval was 1.32-2.10s, P_2-R, P_5-R, P_7-R, P_9-R and P_ (11) R, P_ (13) -R, P_ (15) -R are 0.27s, the basic PR interval, there I ° A-VB. P_1-R = 0.72s, P_3-R = 0.46s, P_4-R = 0.76s, P_6-R = 0.86s, P_8-R = 0.81s, P_ (10) -R = 0.77s, P_ (12) R = 0.84s, P_ (14) -R = 0.84s, PR interval escaping wins, the PR is very long, and R’-P negative feedback relationship with PR.
