PRIMARY outcome

Timeframe: 18 months

Population: Primary analysis of the primary efficacy endpoint for each patient's first episode of PSVT confirmed by adjudication and treated with etripamil NS 70 mg. There were 92 patients who had a PSVT episode that was confirmed by adjudication and were included in the primary analysis.

The efficacy analyses were performed on the Efficacy Population. The primary efficacy variable was the time to conversion of an episode of PSVT to SR after study drug administration.
