Arrhythmias & electrophysiology
Incidence, management, and prognostic impact of arrhythmias in patients with Takotsubo syndrome: a nationwide retrospective cohort study
Authors' conclusion
Arrhythmias are not uncommon in TTS. Patients' background characteristics, rather than arrhythmia itself, may be associated with in-hospital mortality.
Study context
- Population
- Patients hospitalised for Takotsubo syndrome, Japanese Diagnosis Procedure Combination database, July 2010–March 2021
- Participants
- 16,713 patients
- Exposure
