Paramedics say fast-acting staff at the Nepean Sportsplex saved a 52-year-old man’s life.

Just before 8:30 p.m. Saturday, paramedics responded to the Sportsplex gym for a man in cardiac arrest.

Staff had started CPR and used a defibrillator to deliver a shock to the man’s heart, which had stopped beating.

The man’s pulse then returned before paramedics arrived, they said, thanks to a staff member who had only finished his defibrillator training last week.

The man was taken to The Ottawa Hospital’s Civic campus in critical condition.
