Heat Stroke-Induced Takotsubo Cardiomyopathy With a Concomitant Transient Brugada-Like Electrocardiogram.

A 79-year-old man presented with impaired consciousness, fever with a body temperature of 41.1°C, and an electrocardiogram showing significant ST segment elevation in leads V1-6, coved-type ST elevation in leads V1-3, and partial right bundle branch block. Echocardiography revealed notable left ventricle dysfunction with apex-based akinesis. Coronary angiography confirmed severe obstructive lesions but left ventriculography displayed the distinct apical ballooning of takotsubo cardiomyopathy (TC). This case highlights the presence of atypical electrocardiographic patterns in TC influenced by comorbidities, supporting the diagnosis of TC despite concurrent obstructive coronary artery disease.
