Fluorodeoxyglucose positron emission tomography/computed tomography in Takotsubo cardiomyopathy complicated by sinus arrest and third-degree atrioventricular block: a case report

Fluorodeoxyglucose positron emission tomography/computed tomography is valuable for clarifying the metabolic basis of TTC-related myocardial dysfunction, complementing perfusion imaging. Early pacing evaluation is critical for TTC patients with sinoatrial nodal impairment-even with AV nodal recovery, persistent sinoatrial dysfunction may require long-term pacing support to prevent bradycardia-related adverse events.
