marcos,
GL with your surgery!
Cisco, I've got something similar myself! Not frequent but have had "heart-skip" since I was a teenager. Usually happens when I overdose on coffee and/or run in the cold air. Too afraid to go see a doctor about it (haven't been to a doctor or a dentist in years for that matter). GL with your surgery, too!
:)
