Heart Sounds Drill 1

Third heart sound vs. mid-systolic click - Listen

This drill will teach you to tell the difference between a third heart sound and a mid-systolic click.

A mid systolic click is an abnormality of the mitral valve. It has a snapping quality quite different from the third heart sound. Use the listen and learn tab to learn the difference in sound between the two.

Listen as long as you want. When you are confident that you can detect the difference, move on to the test. In the test we will play cycles randomly and ask you to tell which is which.
