Autonomic Modulation in Takotsubo Syndrome (NCT03324529)

Status: Not Yet Recruiting


For Diseases:

  • Takotsubo Syndrome


This is a minimal risk case-controlled single arm intervention study, including 10 patients with a prior history of takotsubo and 10-age and sex matched healthy controls. Subjects will undergo in laboratory testing to measure autonomic function. They will then undergo a 15-week program of device-guided breathing with remote measures of autonomic function obtained at home. Analysis will determine the reproducibility of home autonomic measures and provide preliminary data to determine the efficacy of device-guided breathing on autonomic measures and quality of life in patients with takotsubo.
