According to Breitbart:
A study finds an unborn baby’s first heartbeat occurs as early as 16 days after conception.
A research team funded by the British Heart Foundation (BHF) at the University of Oxford says a baby’s first heartbeat is now far earlier than was previously understood, reports the Daily Mail.
“We are trying to better understand how the heart develops, and ultimately what causes the heart defects that develop in the womb before birth and to extrapolate to adult heart repair,” said BHF professor and lead researcher Paul Riley. “By finding out how the heart first starts to beat and how problems can arise in heart development, we are one step closer to being able to prevent heart conditions from arising during pregnancy.”
