An 82-year-old woman with uncontrolled hypertension and occasional exertional dyspnea was found to be in intermittent left bundle branch block (LBBB). Her laboratory results, echocardiogram, and ischemic workup were unremarkable. This case highlights that intermittent LBBB is not always associated with coronary ischemia, vasospasm, blunt cardiac injury, drugs, and high catecholaminergic or inflammatory states.

一名82岁女性，患有未得到控制的高血压且偶尔出现劳力性呼吸困难，被发现存在间歇性左束支传导阻滞（LBBB）。她的实验室检查结果、超声心动图以及缺血性检查均无异常。该病例突出表明，间歇性LBBB并不总是与冠状动脉缺血、血管痉挛、钝性心脏损伤、药物以及高儿茶酚胺能或炎症状态相关。
