Abstract

A case of transient left posterior hemiblock and various intraventricular conduction disturbances associated with acute anterolateral infarction is reported. The earliest manifestation was an appearance of ventricular premature systoles originated in the area of the left posterior fascicle. On following recordings left posterior hemiblock with periods of high grade A-V block developed. A few minutes later regular alternation of left posterior hemiblock and left anterior hemiblock was recorded in the presence of 2:1 A-V block. The mechanism for such rare manifestation is analysed. After representing complete left bundle branch block, spontaneous recovery of normal conduction was obtained without any change in heart rate.

摘要

报告了1例与急性前侧壁心肌梗死相关的短暂性左后分支阻滞及各种室内传导障碍。最早的表现是起源于左后分支区域的室性早搏。随后的记录显示出现了伴有高度房室传导阻滞的左后分支阻滞。几分钟后，在2:1房室传导阻滞的情况下记录到左后分支阻滞与左前分支阻滞的规律性交替。分析了这种罕见表现的机制。在呈现完全性左束支传导阻滞后，在心率无任何变化的情况下，传导功能自发恢复正常。
