32 weeks, one twin with slower heart rate?

12bailey18 · August 2014

I just got back from my growth scan and everything looks great. Measurements and growth are right on track with both girls. The only concern I had was Baby A's heart rate was 138 and Baby B's was 124. It's not so much that they're different rates that concerns me but 124 seems low to me. The ultrasound tech assured me anything between 120 and 160 is normal. It just bothers me that B's is on the lower end of normal. I see my OB on Friday and they'll check them again. I'm just not sure if I should be concerned even though they both fall in the 'normal' category? Thoughts? Experience? TIA!

Baby A was always a lot slower than Baby B. As long as it's in the normal range, don't worry.

Thanks! I think I'm just getting nervous about every little thing as I'm nearing the end, LOL.

I wouldn't worry. Sounds perfectly within normal range to me. My Baby A's HR is almost always faster than Baby B's. He's a busy boy. lol

You're getting close- so exciting!

My little boy's hovered in the 120's as well. He turned out to be bigger than his twin sister, whose heart rate was almost always 10-20 pts higher. It also depends on who is most active at the time. If Baby B was sleeping and Baby A was moving around, that would make for a higher heart rate also. Don't worry one single iota. Besides, they like to see a lot of variation in heart rates.
