A heart murmur is an extra or unusual sound heard during a heartbeat, caused by turbulent blood flow through the heart valves. Many murmurs are benign, meaning they are harmless and don't indicate a problem. Your doctor will likely ask about any symptoms you might be experiencing, such as shortness of breath, dizziness, or chest pain, though many people with murmurs have no symptoms at all. They might also inquire about your medical history and listen carefully to the murmur's characteristics, like its loudness and timing. It's useful to understand if your murmur is considered "innocent" or if further evaluation is recommended. Seek urgent care if you develop new symptoms like severe shortness of breath, fainting, or chest pain. We invite you to share your journey with a heart murmur.
