Good morning, dear AF co-sufferers! I saw an assistant to my cardiologist recently, and in his report to my GP, he mentioned my 'heart failure'. There were a number of errors in the letter, and my GP said don't worry, he's obviously very new. When I said I was puzzled about the suggestion I'd had heart failure, the GP again dismissed it as an error. However, I've noticed in several recent AFA posts the mention of 'heart failure'. Can anyone clarify what exactly this is, as I imagined it referred to someone being defibrillated and rushed to hospital in crisis - not my situation, thank goodness.
