I have had the week from hell. Sunday morning I woke up heart racing and in afib..Went Sunday night to ER they did cardioveraion and it worked on the first try. So did the other one I had in 2017.Yesterday was different I woke up at 3 am afib again..went to ER last night..5 shocks and I didn't convert.. My blood tests show I am slightly hyperthyroidism again so maybe that's it. Pretty disappointed though and pretty upset about the whole thing..Have you had a successful caeioversion after one didn't work?
Appreciate your time
Kevin
