Key result
Conduction system pacing resolves persistent complete heart block in Takotsubo cardiomyopathy despite systolic recovery.
Why the study?
Atrioventricular conduction disturbances are rare in Takotsubo cardiomyopathy, and the optimal management strategy including pacemaker implantation timing remains uncertain.
Case Report (n=1)
This case highlights that persistent complete heart block can complicate Takotsubo cardiomyopathy and may require conduction system pacing even after recovery of left ventricular systolic function.
Persistent AV block in Takotsubo may require pacing; this case leaves optimal timing and indications open.
Takotsubo cardiomyopathy is a transient form of stress-induced cardiomyopathy triggered by emotional or physical stressors. Although cardiac complications occur in nearly half of patients, atrioventricular conduction disturbances are rare, and the optimal management strategy, including the decision regarding pacemaker implantation and its timing, remains uncertain. We report the case of an 80-year-old woman who presented with Takotsubo cardiomyopathy and persistent complete heart block requiring pacemaker implantation with conduction system pacing despite recovery of the left ventricular systolic function.

Antranik et al. (2026) conducted a case report in Takotsubo cardiomyopathy complicated by persistent complete heart block (n=1). Pacemaker implantation with conduction system pacing was evaluated. Pacemaker implantation with conduction system pacing was required to treat persistent complete heart block in an 80-year-old woman with Takotsubo cardiomyopathy despite recovery of LV systolic function.
