A while back I posted that rough roads were causing my PM's rate response to kick in while I was driving (an 18 wheeler). Today I went to the PM clinic and they changed to sensitivity from medium high to medium low.
Also noted was I had went for 4 1/2 months without any bouts of a-fib then had an almost 2 hour episode yesterday morning (I woke up to it) and one that lasted almost an hour this morning. This mornings bout had happened without my knowing it because I was asleep. I wonder what could have caused them?
