What are the symptoms of a heart murmur?

 Dr. Cathy Provins-Churbock, PhD
Critical Care Medicine
There are not signs or symptoms of heart murmurs per se. Heart murmurs are heard by your health care provider when they listen to your heart with a stethoscope (the rubber tubing they wear around their neck).

Heart murmurs are sounds made by the blood as it passes thru the valves of the heart. A heart murmur may be normal or it may signify an underlying disorder of the heart. An echocardiogram is an ultrasound of the heart that looks at how the valves of the heart are functioning and provide information as to the cause of the murmur. 

If a patient has other signs and symptoms it is of the underlying problem of the heart not the murmur itself. These symptoms may be swelling of the legs, chest pain, or shortness of breath. If you are having these symptoms you should see your healthcare provider for further evaluation.
Most people who have heart murmurs don't have any other signs or symptoms of heart problems. These murmurs usually are innocent (harmless).Some people who have heart murmurs do have signs or symptoms of heart problems. The signs and symptoms may include:
  • Blue coloring of the skin, especially on the fingertips and inside the mouth
  • Poor eating and abnormal growth (in infants)
  • Shortness of breath
  • Excessive sweating
  • Chest pain
  • Dizziness or fainting
  • Fatigue (feeling very tired)
Signs and symptoms depend on the problem causing the murmur and how severe that problem is.
