I'm an M3 and have recently gotten interested in Peds Cardiology as a possible career. However, I don't really have an interest in doing general pediatrics. Would it be a mistake for me to pursue a Peds residency? I guess my question is: Is it a bad idea to go into Pediatrics if you know for sure that you want to subspecialize? Is this investing too much on the hope that future plans - getting into that subspecialty - will work out? Thanks
