I was doing great the first 2 weeks post-op, just an occasional irregular beat here and there (much like before surgery). Then last weekend I started having significant irregular beats, and took myself back to the ER. Even went into A-fib that next morning. And the irregular beats have continued and maybe even gotten worse (went back in a 3rd time even because of it). They keep telling me it's all due to the surgery, healing, swelling, etc. and it'll eventually go away. Which leads me to believe others in here may have had this too. So, my question - I've noticed a distinct difference when standing/sitting up straight vs. reclining or laying down. When standing/sitting up, the beats are almost always quite normal (75 beats per min). As soon as I start reclining or laying down, it doesn't take long before the irregular, and slowwwwww beats start setting in. It drives me crazy because it's going down into the 40's when I lay down, and the pressure this causes is uncomfortable. With the new ticking sound I have, it's very easy to tell when it misses a beat, has an extra beat, etc. I've gotten to where I can pretty accurately tell what my pulse is without taking it (can certainly tell difference between 40's and 75). Has anyone else noticed anything like this? And if so, what the heck is going on???
