Overview

May necessitate device therapy in Takotsubo despite LVEF recovery; leaves open whether conduction disease persists long-term.

Key Points

  • To present a case of Takotsubo cardiomyopathy complicated by arrhythmias, including complete heart block and ventricular tachycardia.
  • Patient presented with syncope and was evaluated using electrocardiogram and echocardiography.
  • Dual-chamber implantable cardioverter-defibrillator was placed due to persistent ventricular tachycardia and heart block.
  • Analysis of electrical stability and autonomic modulation was conducted.
  • Left ventricular ejection fraction was found to be 15%, with significant akinesis and hyperkinesis.
  • Patient exhibited persistent ventricular tachycardia and complete heart block, necessitating permanent pacing intervention.
  • Findings suggest residual electrical remodeling despite recovery of ejection fraction.

Intervention
Dual-chamber implantable cardioverter-defibrillator placement

Takotsubo cardiomyopathy can cause persistent conduction disease requiring device implantation despite reversible left ventricular dysfunction.

Cite This Study

Rivera et al. (2026) conducted a case report in Takotsubo cardiomyopathy with complete heart block and ventricular tachycardia (n=1). Dual-chamber implantable cardioverter-defibrillator placement was evaluated. A 73-year-old woman with Takotsubo cardiomyopathy developed persistent complete heart block and ventricular tachycardia requiring placement of a dual-chamber implantable cardioverter-defibrillator.
