The lub-dup sound is made to signify the opening and closing of the valves in the heart as blood is pumped. The swish is caused by

  • b. A leaky mitral valve

The mitral valve allows the flow of blood from the left atrium to the left ventricle. When the mitral valve becomes leaky, it means that there is a backward flow of blood and there is no proper closing of the valves.

This results in the "lub-swish- dup" beating of the heart. If left untreated, this can result in a cardiac arrest.
