Thank you At 87,and female, I had PAT for 10 years developing AF in 9/13. I am on atenolol, warfarin and vasotec In 2014 I had 3 cardioversions, I ve seen 3 cardiologists for AFib and tachy-brady symptoms, I have not passed out, fainted, and live alone. One cardi. thought AV node ablation and a pacemaker was the best option, the second cardi recommended more cardioversions, and third insisted I have a biventricular pacermaker because a HR in the 40 and 50 s meant heart failure. I have no pedal edema in brady, the HR is 49-54, no SOB with O2 of 98%, no fainting. Your opinion would be welcome.
