Have returned back to thye gym after quite a while to try and lose a bit of weight and improve fitness. G P keen advocate for this but obviously to pay particular attention to my heart rate. Went yesterday and was very alarmed that my heart rate shot up to 178 and took ages to return to normal ( if there is such a thing as normal with having AF) No palpitations but quite nauseous for nearly an hour after finishing exercise. Don't want to give up the gym as I really enjoy going and know it is benefiting me but then if this is going to happen again could it lead to having an AF attack. Medication at the moment bisoprolol 5mg daily, apixaban 10mg daily and rampiril 5mg daily. Any suggestions.
