fetal heart beat

Fetal heart beat can be detected as early as 34 days (just under 6 weeks) gestation on good quality, high frequency transvaginal ultrasound, as a crown rump length (CRL) of as little as 1-2 mm.

If a fetal heartbeat cannot be identified with a CRL ≥7 mm using transvaginal scanning, then embryonal demise can be diagnosed . Demise can be confirmed with repeated scanning and serial quantitative beta-HCG.
