Thanks for response i too am curious how this 14 day thing will go!I will share my results good or bad!
'Trace' regurgitation of valves is nothing to worry about.
I'm not a health professional, and have no understanding of SMA. However, I suspect that you have Brady/Tachy disease, and suspect you might be a candidate for a pacemaker. Your 14 day history will be interesting to all of us, let us know.
