Key result
Permanent pacemaker insertion successfully prevented recurrent torsade de pointes in a patient with persistent long QT syndrome and bradycardia following recovery from Takotsubo cardiomyopathy.
Case Report (n=1)
Permanent pacemaker insertion may be an effective treatment option for patients with Takotsubo cardiomyopathy who develop persistent long QT syndrome and bradycardia-induced torsade de pointes.
May offer option in rare persistent LQTS with TdP post-Takotsubo; hypothesis-generating and should not change practice.
Prolongation of QTc interval associated with Takotsubo cardiomyopathy (TC) has previously been reported in published case series. We report an unusual case of a patient who presented with TC associated with long-QT syndrome and developed cardiac arrest secondary to torsade de pointes. Since QT prolongation and bradycardia persisted after the resolution of TC, the patient received permanent pacemaker. Since then additional event did not occur. QT prolongation and bradycardia could be persistent even after recovery of TC, and permanent pacemaker insertion may be a treatment option of long QT syndrome related with TC.

Ahn et al. (2011) conducted a case report in Takotsubo cardiomyopathy, Long QT Syndrome, Torsade de Pointes (n=1). Permanent pacemaker insertion was evaluated. Permanent pacemaker insertion successfully prevented recurrent torsade de pointes in a patient with persistent long QT syndrome and bradycardia following recovery from Takotsubo cardiomyopathy.
