In A and E after waking up with a pulse of 131. Took an extra Sotalol as advised which restored the heart to rhythm. Exactly the same as happened 7 weeks ago. This has come as a bit of a blow as I didn’t have any problems and thought the Sotalol had dealt with the problem. I guess this is the shape of things to come. And I don’t know how long I had the Afib (or if I had it) when I was asleep.
