Abstract
Myocardial bridges are a congenital anomaly in which a segment of the coronary artery takes a "tunneled" intramuscular course. Few reports have associated myocardial bridges with left-ventricular dysfunction in patients with ischemia. Intermittent left bundle branch block is a conduction disturbance that has been described to be associated with myocardial bridges and cardiac memory. This study reports unusual associations of multiple myocardial bridges, angina, left-ventricular dysfunction, intermittent left bundle branch block, and cardiac memory.
摘要
心肌桥是一种先天性异常，其中一段冠状动脉走行于“隧道”样肌内路径。关于心肌桥与缺血患者左心室功能障碍相关的报道较少。间歇性左束支传导阻滞是一种传导障碍，已被描述与心肌桥和心脏记忆相关。本研究报告了多个心肌桥、心绞痛、左心室功能障碍、间歇性左束支传导阻滞和心脏记忆之间的罕见关联。
