CRT-D and Breathlessness
I cycle raced from 10 to my early 60s with some wins and many races that I have learned made life worth living. In 2005 I had a dual chamber Medtronic inserted and continued to cycle with others. This pacemaker was replaced in 2012 with a dual chamber Boston Scientific. This developed 'noises' in the summer of 2015 and my EF had droped below 35 which qualified me for a CRT . By 'lucky dip' I got a Boston Scientific CRT-D. This was when my exercise tolerance started to tumble both in the gym and on the bike. After three years with a cardiologist who seemed to have no concern about pulses which would not stray beyond the range of 70 - 74 bmp and EFs as low as <25. I changed my cardiologist about 12 months ago. I have seen many in his team and had a 'syncope' in front of one of then which led to my Canasartan being reduced from 8 to 4 mg. Since I had another 'syncope' a fortnight ago and spent a night in hospital I have been taken off Candasartan. My present cardiologist tells my that my heart function as improved 'dramatically' it is just unfortunate that the symptoms haven't. What appears to me as a contradiction is reduced to a conflict between scans and my inability to move without becoming breathless and in discomfort.
Does anyone have any comparable experiences?
