What are the symptoms of Heart Murmur

When talking of the symptoms you should bear in mind that an innocent murmur does not cause any symptoms.

For other types of heart murmurs, symptoms vary depending on the cause. In general, when a heart murmur significantly interferes with the heart's ability to pump blood, you can experience one or more of the following symptoms:

  • Shortness of breath
  • Light-headedness
  • Episodes of rapid heartbeat
  • Chest pain
  • Decreased tolerance for physical exertion and, in later stages, symptoms of heart failure.

Risk Factors

Once again there are not many risk factors involved with an innocent murmur as compared to the ones for the other types. There are in fact risk factors that may increase your chances of a heart murmur, and these are:

  • Family history of a heart defect – When blood relatives have had a condition of heart defect, then it increases yours and your children’s chances of a heart murmur.
  • Illnesses during pregnancy – If in case a person has some conditions during pregnancy, such as uncontrolled diabetes or a rubella infection, then that increases the baby's risk of developing heart defects and a heart murmur.
  • Medications or illegal drugs during pregnancy – The use of certain medications, alcohol or drugs when pregnant can have an adverse effect on the baby, leading to a heart defect.

  • When one has uncontrolled high blood pressure
  • A history of rheumatic fever
  • Past radiation treatment involving the chest
