question: Hello. I recently gave birth to a beautiful baby boy. He s perfect but I am really concerned that he has a slow resting heart rate it could go all the way to 65bpm when sleeping.. When he is up it goes up to 110. He was in the nicu for about 3 days. They were monitoring his heart and they did a EKG on him and said his heart rhythm was normal so they decided to discharged him with no diagnosis. I am so concerned i don t know if to take him to another hospital for a second opinion or to just let it go. He was put on antibiotics due to an infection I had. I m not sure if that s what might have cause it to slow down or what.Could it have been the antibiotics?
