I went to the doctor about 6 months ago and she told me I had a level 3 heart murmur went back today with chest pains and heart palpitations and they did a ekg and said i have a sinus arrhythmia. Gave me a inhaler because they said my lung function isn't normal now going to cardiologist to make sure nothing to serious. I feel like heart murmurs and arrthymia might have a connection?
I have the same problem. I was born with it and have no medical problems except from occasional cold extremities due to mild lack of circulation. There is nothing to worry about and your child will live a long and peacefull life.
You need to ask your question in the doctor's forum. This is a patient-to-patient forum. Click on "forums" at the top of the page, then on "yes I agree," then on "post a question."
From what I've heard, and don't take my word for it, but sinus arrhythmias are usually not something doctors worry about. That's what I've been told by my doctor, anyway.
In any case, try not to make your daughter a hypochondriac until you know for sure if something's wrong.
