患者男性,60岁,临床诊断:冠心病。ECG 系房颤,QRS 形态有3种:Ⅱ导联 R_(4、6、9、17、18、)aVR 导联 R_(2、3)和 V_1导联 R_(2、5、9)宽大畸形为室性搏动,Ⅱ导联 R_(3、12)为室性融合波,其余 QRS 为室上性。室性搏动均以逸搏形式出现,Ⅱ导联 R_(4-6、17、18、)aVR 导联 R_(2、3)为连续出现的室性搏动,R-R 间距为1.32和1.34s,但第1个逸搏和单个出现逸搏则无固定的配对关系,长异位搏动间距(Ⅱ导联 R_6-R_9、R_9-R_(12)、R_(12)-R_(17)、V_1导联 R_2-R_5、R_5-R_9)是短异位搏动间距的倍数,这说明该异位起搏点与主导起搏点
Male patient, 60 years old, clinical diagnosis: coronary heart disease. ECG atrial fibrillation, there are three QRS morphology: Ⅱ lead R_ (4,6,9,17,18) aVR lead R_ (2,3) and V_1 lead R_ (2,5,9) large deformity Ventricular beating, Ⅱ lead R_ (3,12) for the fusion of the chamber, the rest of the QRS for the supraventricular. The ventricular beats occurred in the form of esophageal stroke. The R_ (2, 6, 17, 18) aVR lead of Ⅱ lead was continuous ventricular beats with RR intervals of 1.32 and 1.34 s The first esophageal aneurysm and single esophageal aneurysm showed no fixed pairing relationship. The distance between long ectopic beats (Ⅱ lead R_6-R_9, R_9-R_ (12), R_ (12) -R_ (17) R_2-R_5, R_5-R_9) is the multiples of the short ectopic beat spacing, indicating that the ectopic pacemaker and dominant pacemaker
