By Mayo Clinic staffIf you have a harmless heart murmur, more commonly known as an innocent heart murmur, you likely won't experience any signs or symptoms.
An abnormal heart murmur usually has no obvious signs, aside from the unusual sound your doctor hears when listening to your heart with a stethoscope. But when these signs or symptoms are present, they may indicate a heart problem:
- Skin that appears blue, especially on your fingertips and lips
- Swelling
- Shortness of breath
- Enlarged liver
- Enlarged neck veins
- Poor appetite and failure to grow normally (in infants)
- Weight gain (in adults and children)
- Heavy sweating with minimal or no exertion
- Chest pain
- Dizziness
- Fainting
