It’s difficult to describe... I’ve had a lot of exercise recently but feel really depleted, more than I think I should. Excess muscle farigue too. Plus there’s a kind of feeling of breathlessness but I’m not actually breathless and some awareness of my heartbeat. I had an ablation for occasional Afib about a year ago and it’s seemed successful so far. I detect no irregularity or particularly fast beat. I’m considering taking a flecanaide. Is there any point? Any opinions out there please? I’ve had sufficient experience to not be panicking or rushing to a doc unless it continues tomorrow or worsens.
