My son was diagnosed with an irregular heartbeat when he was 6. This was discovered during surgery while he was having eartubes put in and adenoids removed. The surgeon came out to talk to me, and was very concerned. She told me that I needed to get him to his pediatrian immediately and have him referred to a pediatric cardiologist. I was terrified. No one had ever mentioned any problem with his heart before.
I followed all instructions. We went to the cardiologist the next week and had several tests done. It took about a week to get results, and everything was fine. There is absolutely nothing wrong with my son's heart. I asked the cardiologist why the surgeon was so concerned, and he said it happens pretty often. The surgeon isn't a heart doctor. Something didn't sound right, and the surgeon needed to err on the side of caution. I'm glad to know that everything is fine, but it sure was a stressful couple of weeks. I hope everything is fine with your daughter, too.
