摘要

患者55岁，表现为稳定型心绞痛，静息心电图和心脏超声心动图检查正常。跑步机试验显示运动引起的左后束传导阻滞，这是冠状动脉疾病的一个不常见且容易被忽视的标志。进行了多巴酚丁胺应激超声心动图，结果明显阳性。冠状动脉造影显示右冠状动脉严重狭窄。

Exercise-induced left fascicular block: A forgotten sign of coronary disease

A 55-year-old patient presented with stable angina pectoris with normal physical examination on rest electrocardiogram and cardiac echocardiogram. Treadmill test revealed exercise-induced left posterior fascicular block, which is an uncommon and easily unnoticed marker of coronary artery disease. A dobutamine stress echocardiogram was performed, with a clearly positive result. Coronary angiography revealed critical stenosis in the right coronary artery.
