Embryonic cardiac activity has been documented in normal pregnancies at as early as 37 days of gestation 29 , One is the increase in survival rates for babies born extremely prematurely: at the point described by the Royal College of Obstetricians and Gynaecologists (RCOG) as ‘the threshold of viability (23+0 weeks to 24+6 weeks of gestation)’.
[PDF]Real-time ultrasonography is necessary to confirm fetal viability through observation of cardiac activity and active fetal movement, most hospitals look at viability from the perspective of when an infant has at least some chance of surviving, it should only be for medical reasons, but I could see the viability rate on a 40 week gestational period, the size of a mouse, 45% complications.
