Valve sounds

Authoring team

Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle. Vibrations of these structures from the blood flow create audible sounds - the more turbulent the blood flow, the more vibrations that get created.

They include:

  • the first and second heart sounds
  • ejection sounds
  • opening snaps
