UPDATE:
We just got home and they were unable to find a blockage so that's GOOD NEWS! The dr was unsure now what is causing the a-fib but thinks it is one of those things that just doesnt' have a 'cause'. He will remain on his meds and go see the cardio dr on the 22ond and it looks like our 30th wedding anniversary trip is still ON!
Thanks for ALL the good wishes everyone....those did get me through the day!!!
Blessings
