Embryonic cardiac activity should be detectable transvaginally when the embryonic crown rump length is 5 mm or more. Absence of sonographically detectable embryonic cardiac activity when the crown-rump length is greater than 5 mm is compatible with embryonic demise. Between 5 and 8 weeks, the heart rate is usually 100 beats/min or greater.Crown-Rump Length The fetal pole, or embryo, can be consistently visualized by transvaginal scanning at a size of 5 mm, but can be detected when as small as 2 mm.

Crown Rump Length: Gestational age = 6 weeks plus (CRL x days). This relies on the growth of the normal fetus of 1 mm per day after the 6th week of gestation. For example, a CRL of 16 mm would correspond to a gestational age of 8 weeks and two days (6 weeks plus 16 days = 8 weeks and 2 days).
