Hi all. My lone fast PAF has happened approx 14 times over last year, and an episode can last between 3 and 15 hours, always at night lying down. Have been on on 1.25 Bisoporol twice daily. Started Flec 300mg as PIP early Jan after first trying in hospital last Oct. Seemed to be a true wonder drug to me, back in NSR in less than an hour. then 2 weeks later took it again, same great result, but then I went into Fast AF again the next day, then 2 days later, a total of 7 Fast AF episodes almost daily for 9 days, it had never happened this often before, and unwisely I was taking the Flec each time, it worked well, sometimes in 15 mins! but then on the 7th time taking Flec in 9 days things went very badly, while waiting for it to work I started to feel a really heavy crushing feeling all over, became very weak, couldn't stand up, body tingling all over, terrible aches in back of neck, sudden sweating, my vision went completely sparkly (pretty but scary!) my nose and ears went stone cold, no idea what was happening, thought I might be have a stroke or worse... called ambulance, came in 6 mins! (and in Cornwall too!), carried out of the house, blue lighted all the way to hospital, self corrected on arrival... Spent next 3 days in the Cardio ward. I knew it was the Flec, seems I went into some kind of Ventricle Tachycardia or Abberant AF? and that had caused extreme low blood pressure. Cardiologist agreed it was the Flecainide so stopped that, had 2 episodes a day for next 2 days, self correcting each time 3 6 hrs, ..... So now back at home, just on Bisoporol again, upped to 3.75mg daily, AF free now for 3 weeks. So hopefully back to the previous normal. It was obviously a mistake for me to be taking the Flec every day, but as I knew some are on it daily assumed it would be OK. Generally I don't feel like I get much monitoring or support or info from NHS, and am just left to work things out myself. But maybe this is just how it is with AF?
