Cardiac activity is visible beginning at approximately 5 weeks of pregnancy. The human heart begins beating at a rate near the mother's, about 75-80 beats per minute (BPM). The embryonic heart rate (EHR) then accelerates linearly for the first month of beating, peaking at 165-185 BPM during the early 7th week, (early 9th week after the LMP).
At 21 days after conception, the human heart begins beating at 70 to 80 beats per minute and accelerates linearly for the first month of beating. Fetal heart rate monitoring. 30 weeks pregnancy. The human heart beats more than 2.8 billion times in an average lifetime. [ 60 ]
The heart is the first functional organ to develop and starts to beat and pump blood at around 22 days. [21] Cardiac myoblasts and blood islands in the splanchnopleuric mesenchyme on each side of the neural plate give rise to the cardiogenic region.

A six-week abortion ban, also called a "fetal heartbeat bill" by proponents, is a law in the United States which makes abortion illegal as early as six weeks gestational age (two weeks after a woman's first missed period), which is when proponents claim that a "fetal heartbeat" can be detected.
A normal nonstress test will show a baseline fetal heart rate between 110 and 160 beats per minute with moderate variability (5- to 25-interbeat variability) and 2 qualifying accelerations in 20 minutes with no decelerations. "Reactive" is defined as the presence of two or more fetal heart rate accelerations within a 20-minute period. Each ...
The so-called "fetal heartbeat ban" prohibits an abortion once the first sights of cardiac activity can be detected in a pregnancy. That can occur as early as six weeks of pregnancy — or just ...
The law will ban most abortions after cardiac activity is detected. Here's what you need to know about the law, its exceptions and legal challenges.
