I just googled PAC in fetus cardiac and there were a few good sites. The stated that 99% of cases are not associated with underlying structural problems and less than 1% go on to have other issues. The management seems to be regular monitoring of the babies heart rate which you would have at check ups. Please call your health care provider Monday and let them know your worried, they often font explain things in enough detailso we font go away worrying ourselves sick about them.

My 1st DD had an unusual hinging on her ultrasound which was harmless but I still worried about it for weeks
