Sorry to inflict my grumbling on my fellow sufferers, but I feel a lot of you will understand. My cardiologist took me off Flecainide and substituted it with Bisoprolol 18 months ago. I was taking a 1.25mg dose daily, so the minimum dose. On check-ups I told him that my heart rate had lowered with Bisoprolol to about 45 bpm and it left me feeling tired and generally run down with several episodes of ectopic beats which resulted in dizzy spells. Last September he arranged for me to have a 24 hour Holter tape. I heard nothing, so assumed he was happy with the results. When I saw him in clinic last week he told me to stop taking Bisoprolol immediately as my night time heart rate went down to 34 bpm on the tape readings. My concern is that there was 9 months between me having the tape on and me seeing him again. Why was I not called back to clinic when he saw 34 bpm on the results? He has left me for 9 months taking a drug which, in his own words, gave me a dangerously low heart beat. I am disappointed in him. Sorry for the rant.
