Hi bbycswt,
I agree with Momto3-there is absolutely nothing you did to cause the arrythmia. It sounds like they have everything under control. They are telling you this is benign which would is very reasssuring . If you're still concerned, you could talk to your OB/GYN and ask if you could speak to a pediatric cardiologist just for your own peace of mind. I'm betting they'll tell you it's nothing serious too.
Hi bbycswt,
You are not responsible for your baby's arrythmia. Don't give that a second thought. Arrythmias are very common, so trust the doctors and continue to take good care of yourself and your little one. I'm not a doctor, but I don't think what's going on is serious. Take care and if you're still concerned, talk it over with your OB.
