摘要
4相传导阻滞是心率减慢、心动周期延长时出现的阻滞现象,又称慢频率依赖性阻滞,包括4相性束支传导阻滞和4相性房室传导阻滞。本文就1例4相左束支传导阻滞伴紊乱性房性心动过速患者进行分析,以期对临床有所帮助。
4 phase block is a phenomenon of slowing of heart rate and obstruction of cardiac cycle.It is also called slow frequency dependent block.They consist of 4 phase bundle branch block and 4 phase atrioventricular block.1 patients with 4 phase left bundle branch block with paroxysmal atrial tachycardia were analyzed in this paper.
