First symptoms that something wasn’t right - Atrial Fibrillation

David, you were eventually diagnosed with atrial fibrillation. How did that journey start? It started about 2012 when I thought I noticed an irregularity in my heart rate. It was checked out thoroughly, completely, totally and no one could find anything. I then subsequently thought I was losing fitness and I kept telling myself I'm not swimming enough, I'm not cycling enough, I'm not doing this. Just walking up a flight of stairs and having a conversation was getting a bit breathless. Then I started having a very dry cough, persistent but not major. It piggybacked on a chest infection in March 2016, and I blacked out. I got into the A&E at West Middlesex where I was told I had AFib. I was more worried about the cough, but that's the first identification, solid identification that I had AFib.
