Takotsubo cardiomyopathy is a recently described syndrome characterized by reversible left ventricular dysfunction, chest pain, ST-segment elevation, and minor elevation in serum levels of cardiac enzymes, in the absence of significant coronary artery disease. ST-segment elevation is the most common electrocardiographic finding on the admission ECG of patients, followed by evolutionary T-wave inversions. We report a case of takotsubo cardiomyopathy characterized by the unusual feature of a new onset transient left bundle branch block as first electrocardiographic manifestation. New left bundle branch block increases heterogeneity in the broad spectrum of electrocardiographic findings of takotsubo syndrome, contributing to ambiguity in the early recognition and affecting potential management strategies.
应激性心肌病是一种最近才被描述的综合征，其特征为可逆性左心室功能障碍、胸痛、ST段抬高以及血清心肌酶水平轻度升高，且不存在显著的冠状动脉疾病。ST段抬高是患者入院心电图最常见的表现，其次是动态T波倒置。我们报告一例应激性心肌病病例，其特征是首次心电图表现为新发短暂性左束支传导阻滞这一不寻常特征。新发左束支传导阻滞增加了应激性心肌病广泛心电图表现谱中的异质性，导致早期识别存在模糊性，并影响潜在的治疗策略。
