Although Takotsubo cardiomyopathy (TC) is often linked to various tachyarrhythmias, the coexistence of Takotsubo cardiomyopathy and complete heart block is rare, and the cause-and-effect relationship remains unclear. We present the case of an 83-year-old female with a history of known second-degree atrioventricular (AV) block who presented with syncopal episodes and bradycardia. She was diagnosed with a complete heart block requiring a dual-chamber pacemaker. Upon case review, transthoracic echocardiography revealed severe apical hypokinesis, prompting coronary angiography, which showed normal coronary arteries, consistent with Takotsubo cardiomyopathy. This case explores the relationship between Takotsubo cardiomyopathy and complete heart block, as well as the potential pathophysiological mechanisms involved.
