A member asked:
How early can a baby's heartbeat be detected? or is 5 weeks too early?
A doctor has provided 1 answer
Too early: The heartbeat is created by the sound of valves closing against pressure. At 5 weeks a babies heart is still forming & consists of incomplete upper & lower chambers with no valves. By 8 weeks there are valves, but their closure does not generate enough sound to be detected by most methods.
