Took on board all the comments about rapid response. I went back to the cardiologist saying about the fast heart rate and how I was feeling. I have been fined tuned - he turned down the response and as soon as I got off the table I felt that awful feeling in my stomach gone. Also went for a walk this afternoon and not one funny session.
I have been put on a tablet for a month as well - sort of beta blocker - and am due to see him again on the 22nd Feb.
Hey light at the end of the tunnel.
Thanks guys for all the input.
