I have heard from Nick.
He is recovering and expects to be out of Hospital very soon.
Long story short...he did not have a typical Heart Attack and in effect there is no damage to his Heart as a result of what happened.
He has had a De-fillibrator installed which should prevent any catastrophic events as he experienced in Church last Sunday.
He described it as being a Hereditary Malady that can be passed down and is usually discovered prior to about age Forty.
The very good news is the lucky Sod managed to find the exact right time and place to have that problem manifest itself....something like seven Doctors sat around him in the Pews....one being a Cardiologist.
He expects to be back at work in a week or so but the bad news is he has permanently lost his Medical.
I am sure he will be along to tell us of his progress.
