I have had very short episodes of heart palpitations since I was in my twenties (I'm now 64) and was told I had an irregular heartbeat when in my early forties. Ever since I contracted a nasty virus 8 weeks ago, I have been in AF. This wasn't diagnosed by my Doctor until 4 weeks ago as he wasn't convinced until I had my third ECG. I am being monitored with Warfarin and I'm taking Diltiazem which has only decreased my heart rate to around 90 bpm. I'm getting really worried because the promised heart scan hasn't come through yet and I know the longer I am in AF the harder it is to get out of it. Maybe I was being optimistic when I thought I would be given a scan almost straight away! I keep hoping I will suddenly come out of AF but, as the days go by, I'm losing that hope. I'm also worried that there could be something wrong with my heart....that hasn't been looked at yet. Any advice?
