This audio only movie is a realtime recording of the GA week 17 fetal heart rate and heart sounds.

The characteristic "lub-dup" sounds are associated with closing of heart valves.

  • First sound (lub) occurs as atrioventricular valves close and signifies beginning of systole (contraction).
  • Second sound (dup) occurs when semilunar valves close at the beginning of ventricular diastole (relaxation).

There is both a tutorial and development information page for cardiac valve development.
