Human Fetus (GA 17 week) heart beat

This audio only is a realtime recording of the [[Timeline_human_development#Second_Trimester|week 15 (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).

Heart Valves

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

Atrioventricular valves	Semilunar valves
