心房纤颤伴3相左束支阻滞少见,现将我们见到的一例报告如下:患者,女,75岁。风心病史50余年、冠心病史10余年。本次因阵发性胸痛、心慌加重一天来诊。心电图(图1,V_1、V_5为同步描记)示心房纤颤,R—R 绝对不整,QRS V_5大致可分为3种形态: 一种相对“正常”呈不完全性左束支阻滞,如R_1、R_4、R_9;另一种为完全性左束支阻滞,如R_2、R_3、R_5—R_8、R_(10);第三种R_(11)呈Rsr′型。图形相对“正常”者出现于较长的R—R 之间,周期长度0.61—0.64秒,QRS 时限0.10秒;左束支阻滞图形发生于较短的R—R 之间,周期长度0.48—0.59秒,QRS 时限0.12秒;第三种R_(11)发生于最短的R—R0.42秒。Tv_5负正双向或直立,为原发性T
Atrial fibrillation with 3-phase left bundle branch block rare, now we see a report as follows: Patients, female, 75 years old. History of rheumatic heart disease more than 50 years, history of coronary heart disease more than 10 years. This due to paroxysmal chest pain, palpitation day to diagnosis. ECG (Figure 1, V_1, V_5 for the synchronous tracing) shows atrial fibrillation, R-R is not the whole, QRS V_5 can be divided into three forms: a relatively “normal” incomplete left bundle branch block, such as R_1, R_4, R_9; the other is a complete left bundle branch block, such as R_2, R_3, R_5-R_8, R_ (10); the third R_ (11) Rsr ’type. The relative “normal” pattern appeared between longer R-Rs with a period length of 0.61-0.64 seconds and a QRS duration of 0.10 seconds; the left bundle branch block pattern occurred between shorter R-Rs with a period length of 0.48- 0.59 seconds, QRS duration 0.12 seconds; the third R_ (11) occurred in the shortest R-R 0.42 seconds. Tv_5 negative positive bidirectional or erect, primary T
