Anyone suffered from an irregular heartbeat due to anxiety/stress? I've spent the day in A&E having been suffering from an irregular heartbeat - they've said I'm not in immediate danger (after bloods and ecg) but will need a 24hour trace as further investigation. I have been under a LOT of stress and have been extremely anxious in recent months - my gut says this is the route of my problem. Especially given I'm in my 40s, slim and very fit - don't drink at all and have never smoked. Has anyone else had an irregular heartbeat?
