病历摘要及心电图分析患者男性,63岁,冠心病,高度房室传导阻滞,偶有晕厥。本文附图是安装“秦明8619 VVI”起搏器后一个月非同步记录的三个标准导联心电图。起搏器体外程控频率80次/分,起搏的心室波为完全性左束支阻滞(CLBBB)型伴电轴明显左偏,其宽度为0.16s。患者自身心律为窦性心律伴CLBBB,平均电轴不偏,其QRS宽度为0.12s。Ⅰ的R_(1,4)、Ⅱ的R_(1,2)和Ⅲ的R_(1,2)是自身心搏的心室波群;Ⅰ的R_(10～12)、Ⅱ的R_(9～12)和Ⅲ的R_(10～12)是完全起搏的心室波群;其余都是不完全起搏的心室波群,即室性融合波。这种融合波是由起搏冲动和窦性夺获心室冲动共同除极心室而形成的,故称为“起搏——夺获室性融合波”(pace-capture ventricular fusion wave)。又因这种融合波时限比单独起搏和单独夺获的心室波要短(尤其是标有“↑”者,约
Summary of medical records and ECG analysis of patients Male, 63 years old, coronary heart disease, atrioventricular block, occasional syncope. This document is the three standard lead ECGs recorded asynchronously one month after installation of the “Qin Ming 8619 VVI” pacemaker. Pacemaker in vitro program-controlled frequency of 80 beats / min, pacing of the ventricular wave for the complete left bundle branch block (CLBBB) -type axis of the apparent left-deviation, the width of 0.16s. Patients with their own rhythm of heart rhythm with CLBBB, the average electric axis is not partial, the QRS width of 0.12s. The R_ (1, 4), R_ (1, 2) and R_ (1, 2) 12) and Ⅲ R_ (10 ~ 12) is a fully pacing ventricular wave group; the rest are incomplete pacing of the ventricular wave group, that is, ventricular fusion wave. This kind of fusion wave is formed by pacing impulse and sinus ventricular impulse decoupling. Therefore, it is called “pace-capture ventricular fusion wave”. Because of this confluence wave limit than single pacing and seizure of ventricular wave is shorter (especially marked “↑”, about
