unfortunately i do not know anything about your heart murmur. there are many different types and causes. before starting an exercise program it is a good idea to get the "okay" from your doctor or have an exercise ecg (stress test). you will need to consult your doctor -- someone who knows your medical history.
will exercise affect my heart murmur? . i try to work out at least 3 -5 hours a week. i get tired but keep going. will this cause any damage?
