Bob, I also have the BP cuff and Kardia Mobile. When my HR was so high right after my surgery the specialist stopped my heart with a radioactive isotope through my IV. Nurses came running from all over the hospital to watch since they had never seen the procedure done. It was quite bizarre to see my monitor flat line for several seconds, not a breath being taken in the room, then kick back in, collective exhale. Unfortunately, it didn't fix the problem. When the AFIB became constant several weeks later I was scheduled for cardioversion. Went in, got prepped, my cardiologist walked in, looked at the monitor and said he didn't see any AFIB. He asked if I had had any type of stressful, bear-down (like taking a tough dump) situation lately. Told him my dog Payton (who we think might be a small part wolf) occasionally challenges me and we have to have a "come to Jesus moment" which becomes very physical and intense. Doc told me it looked like my dog fixed my AFIB.
I've been on Plavix for a few years and my Doc just switched me to Eliquis the day he called about my AFIB.
At my last cardiologist visit I asked what problems we might be looking at. He said it could be new blockage, or leaky valve, or weakened heart muscle, or maybe I'd need a pacemaker, or an electrical problem, or ......we'll see what the tests show.
