Hi!
I also had this happen with baby number 2 along with many other pregnancy complications. My first son had VSD(2 holes in his heart) so we were particularly worried and also had an echo of her heart. Everything with her heart was fine and it went away right after birth just as they said it probably would. Even if it doesn't the specialist at Loyola said it is not a big deal and would be controlled by the pediatrician with medicine if neccessary. The irregularities made it very hard for me to be on the monitirs for a NST!!(For other issues). Hang in there it will turn out fine!
