heartrates healthy???

I had a scare this morning, ended up panicked & in the er. Both babies still have beautiful beating hearts. Baby A, the one in the larger sac has 132 beats per minute & baby B was 127 per min. Baby B is measuring 3 days smaller than A and A's sac is really large. Are those pretty healthy rates?

I found this...

The normal fetal heart rate usually varies somewhere between 120 and 160 beats per minute (bpm) throughout pregnancy, but in the early part of the first trimester, the baby's heart rate can be slower. A 1996 study established the following as the minimum normal heart rates in early pregnancy ultrasounds, with the size varying by the size of the fetal pole:

2 mm embryo: 75 beats per minute
5 mm embryo: 100 beats per minute
10 mm embryo: 120 beats per minute
15 mm embryo: 130 beats per minute

from what I read faster is better to a point. The thing that would be concerning is if they were slow...but yours are in the normal range it looks like :)

I don't know if this helps at all but I have had two boys and the baby on the way is averaging about 135bpm at 14 weeks.  All of our children have stayed close in this range when we were pregnant, but I have read if you are having girls that the heart rates can tend to be on the higher end.  I do use a at home doppler though which has helped ease my mind for the first trimester.
