Heart murmur at 2 year check up

Tiffany

Our daughter had her 2 year check up today. She was very nervous, but sat quietly and watched while the doctor checked her heart. He said her heart was racing, which is expected considering how nervous she was, but he also heard a heart murmur. He said he isn’t worried because he hasn’t heard before now, but we still need to get it checked. So he’s referring us to a cardiologist.

I was just wondering if anyone else has had this happen? What did they do at the cardiologist? And how serious was it?

Thanks!
