  • The safety of self-administered etripamil Nasal Spray (NS) for treatment of episodes of PSVT outside of the clinical setting as assessed by patient-reported adverse events.

    Up to 3 years

Study Arms (1)

Etripamil NS 70 mg

EXPERIMENTAL

Self- administration of a dose of 70 mg of etripamil. Patients will be provided with a maximum of 4 pre-filled devices at a time.
