I'm having b/b twins and their heart rate baselines range from 135 to 150 and they spike down to 105 and up to 185 during accels and decels. They are rarely right at the same rate.

Yeah you ladies rock. Thank you for your input. Maybe there is hope for b/g yet. Either way I know I will be happy.

I am having b/g twins and their heats beats are very close. Last appt one was 147 and the other 145.

I have b/g twins and my boy's heart rate is always faster than hers. He's also the more active one.

I am having b/g twins and their heart rates are almost identical at each appointment. Started 175ish and are usually now around 150s

I have two girls and one can be as low as 140's and as high as 170's. Just depends on any given moment how active they are.

I agree-don't think heart rates tell a lot. At my US they are very close and having b/g twins and even at Nonstress tests they are always hard to tell apart

Mine are both girls and their heart rates differ every time. Its usually because 1 is active and 1 is asleep so Im not sure that you can tell much from just the HRs alone
