Have had PAF for over 8 years. Episodes have been few and far between. In June diagnosed with Brady and tachycardia and had pacemaker inserted in August. Have had 1 bad PAF episode since then. Have been prescribed Apaxiban 5mg x 2 daily and Bisoprolol 2.5mg x 1 each morning since pacemaker. Made contact recently by email to cardiologist/EP consultant asking if ok to take an extra Bisoprolol tablet if PAF reared its head. Was given the go ahead. Next appointment not till September 2016. For the last two nights, settling down to sleep when palpitations reared their head. They were not as severe as previous episodes, lasted about 2-3 hours and I was able to cope with them. I did not take an extra Bisoprolol as middle of night. Should I have done so. I am now beginning to worry that this is going to be an every night occurrence. I would appreciate your thoughts and advice please. Sorry that this missive is so long winded.
