I have had 2 episodes of AFIB, both at night when in bed. The first one lasted for 7 hours, went to doctors surgery, had ECG which was normal. The second episode was about 6 weeks later again in bed in the night. This one lasted for 11 hours and I was able to get to my doctors surgery in time to catch it on an ECG trace which confirmed Paroxyismal Artrial Fibrillation. I have recently seen a consultant who wants me to take 100mg of Flecainide and 90mg of Diltiazen SR. He has prescribed this medication having only viewed my ECG Trace and without doing any other tests, although he is intending to do an Echocardiogram and treadmill test in about a month.
