WEBMay 16, 2022 · Overview. What is a heart murmur? When your heart beats, valves open and close, allowing blood to flow. When the valves close, they produce two sounds: a “lub” and a “dub.” If your heart makes a whooshing or swishing sound instead, that’s called a heart murmur. A murmur means blood is flowing abnormally across your heart valves. grading
