Pacemaker fitted after periods of dizziness and blackouts, I have being feeling unwell for the last eight to ten weeks with periods of AF meds increased bisoprosol 5mg and Flecanide to 100 mg this caused more problems and my dose dropped to 2.5 and 50 still haveing problems. Then started to get very dizzy and blood pressure low heart rate sometimes as low 30 to 45 bpm symptoms increased in frequency and then blacked out several times last being at work ( engineer in hospital) cardiology managed to capture event which showed I was haveing extra beats followed by pauses of three to five seconds put on r test over bank holiday weekend which confirmed findings. Booked in for pacemaker and fitted on the 1st September now my heart rate can't drop below 60 bpm still experiencing palpatations but feel a lot better. Found out medics move quite quickly when you start to black out. Drs think I might have sick sinus syndrome.
