I just wanted to say that my DS's heartrate between 7wks6d and term varied between 173pbm (at term) and 181bpm (at 12wks) and he is ow a very healthy and extremely active 2 year old.

With my current pregnancy, the HR has varied between 115bpm and 143bpm depending on what she is doing.

Each baby and pregnancy is different and as long as it isn't over 190bpm for an extended period of time then bub will be fine.
