Episodic (transient/ intermittent) left bundle branch block (LBBB) has been associated with different conditions such as bradycardia, tachycardia, anesthesia, acute pulmonary embolism, changes in intrathoracic pressure, chest trauma, cardiac interventional procedures, mad honey poisoning, and in other clinical settings. Of note, exclusion of an acute coronary syndrome in the setting of episodic LBBB is of great importance. Moreover, episodic LBBB is sometimes symptomatic and may be associated with left ventricular systolic and/or diastolic dysfunction or conduction disturbances leading to syncope. This review article provides a comprehensive overview of the conditions associated with episodic LBBB and discusses the clinical impact of this phenomenon.
间歇性(短暂性/间歇性)左束支传导阻滞(LBBB)与多种不同情况相关,如心动过缓、心动过速、麻醉、急性肺栓塞、胸内压变化、胸部创伤、心脏介入手术、疯蜂蜜中毒以及其他临床情况。值得注意的是,在间歇性LBBB情况下排除急性冠状动脉综合征至关重要。此外,间歇性LBBB有时会出现症状,可能与左心室收缩和/或舒张功能障碍或导致晕厥的传导障碍有关。这篇综述文章全面概述了与间歇性LBBB相关的情况,并讨论了这一现象的临床影响。
