Thank you for replying. My other doctor said I could have a heart valve problem caused by the heart murmur. Can this be possible? Also I have Rugby practice next week and I have to get my echocardiogram this Friday, will it be safe to go to practice? Also, when I found out I had a heart murmur, I still went to practice and my heart was beating even faster thatn it usually beats when I exercise. It waa still beating faster even several hours after practice.
