I am diagnosed by civvy cardiology dept as having irregular heartbeat. They advise me don't do heavy exercise etc. (My BP is a little high also at 170/110. I'm 42 years old). As a Reservist I was due to deploy on a short exercise in Falklands in spring but my unit grounded me from long haul flights pending seeing an Army specialist who will document what I can and can't do. I'm waiting to see a cardiologist at Frimley Park. Has anyone got this condition and what was your experience? Has anyone got specialist knowlege and what may be the likely outcome for me?
