when does a fetus have heartbeat
The fetal heart is a lot different than a newborn heart. A fetus does not use their own lungs until they are born so they fetal heart does not pump blood through the lungs in order to collect oxygen. Just a few weeks after conception, the fetal heart takes up the majority of the fetusâ very small body. The heart resides high in the chest, but after a few more weeks will move down to its normal position in the chest cavity. The fetusâ heart begins to beat at 5 weeks gestation, at around 80-85 beats per minute. This rate increases about 3 beats per minute per day during the first month.
