A member asked:

I have a hx of recurrent pregnancy loss. i am 11 weeks pregnant. md checked the heart beat at 10 weeks via ultrasound. would a chromosomal abnormal baby have a regular heart beat at 10w, or would it be slower or faster?

A doctor has provided 1 answer

Fetal heart rates vary from minute to minute, and do not correlate with chromosomal abnormalities in general. If concerns exist about fetal chromosomes, ask your OB physician about a genetic study via amniocentesis or placental sampling.
