A young woman has the quick work of bystanders and emergency crews to thank for re-starting her heart at Algonquin College Wednesday evening.

Ottawa paramedics said they were called to the Algonquin College athletics dome around 7:25 p.m., where a 20-year-old woman was in cardiac arrest.

Ottawa fire officials said their crews arrived first and took over from bystanders performing CPR to give her a shock from their defibrillator.

Paramedics treated her further when they arrived, re-establishing a heartbeat and getting her breathing on her own before she was transferred to hospital staff.

A free CPR course is being offered by paramedics on Dec.6 if you’re interested in learning - details are on the city’s website.
