Heart murmurs are sounds during your heartbeat cycle — such as whooshing or swishing — made by turbulent blood in or near your heart.

Most you don’t need to worry about and don't require any treatment.

But there are exceptions. Murmurs can be linked to a damaged or overworked heart valve. Some people are born with valve problems (congenital heart disease). Others get them as a part of aging or from other heart problems.
