Dual Chamber pacemaker impacting Ejection Fraction Ratio
I had a Boston Sceintific Dual chamber pacemaker installed in Nov 2019 due to 2:1 heart block. Post pacemaker implant, a PET/SCAN revealed inflamamtion in heart for which I got a Prednisone & Methotrexate treatment. Although the inflmamtion is now completely gone after 1.5 years recent echo revealed that my Ejection fraction ratio dropped to 45% from 60% (at the time of pacemaker implant). Also teh 2:1 block has now changed to full block., so pacemaker is used 100%.
Doctor is advising to go for change in pacemkaer to bivertinicular as they think sometimes dual chamber pacemaker being used 100% can impact left side being out of sync. Has anyone gone through similar scenario. Does CRT treatement really helps. I am also on medication (beta blocker and ACE inhibitor). Does medication help in increasing EF ratio or do I have to go for CRT. Thoughts?
