Had a bloke on the radio who was out for a run and then woke up in hospital.
Doctors were saying ‘We think your heart rate dropped and you passed out, it was very low when you were brought in’.
Bloke ‘No, no, I’m an athlete my resting heartrate is always low – my resting pulse is below 35’
Dr: ‘Does it normally go down to 1?’
Bloke: ‘Gulp’
he had a pacemaker fitted.
As above a specific resting heart rate is not an indication of a healthy (or otherwise) heart.
Same happened to a friend of mine. He was a very competitive runner but started to have similar blackouts.
He had a couple which left him injured, one hospitalised when he collapsed running with friends and hit a wall at quite a speed.
He has a couple of young children so although he went through a range of tests which were inconclusive he decided to stop exercising at such an intensive level.
Shame really but he couldnt take the chance of ending up under a bus!
