Three doctors cycling behind a 45-year-old man rushed to his aid after the man suffered a possible cardiac arrest while biking down Wellington Street on Saturday afternoon, paramedics said.

The man fell off his bike at about 2 p.m. near Bay Street. The three doctors — including a cardiologist — were cycling behind him at the time and immediately stopped to help. The man had no pulse, said paramedic Supt. Michael O'Brien, and the doctors began CPR.

An OC Transpo special constable driving nearby rushed to the scene with a defibrillator and the cyclist was given an electrical shock.

Paramedics arrived along with firefighters and took over patient care. The man regained consciousness and was awake and talking while he was being taken to hospital in an ambulance.

"That's about as good as it ever gets, and pretty rare," O'Brien said.
