Is my baby's heartbeat slow?


Hi everyone,

I might just be looking into this too much, but today I had a transvaginal ultrasound and the tech counted the HB (heartbeat) as 124 per minute. I am 7w3d. does anyone know if this is normal? why do I feel like it is slow? I checked online and I could not find much information. The tech said it was fine, but I saw on a different forum that many woman had fetal HB's at around 140 at 7 weeks. any advice is greatly appreciated!!!!

Here is what I found online for you:

Starting at week 5 the fetal heart will accelerate at a rate of 3.3 beats per day for the next month.

The fetal heart begins to beat at approximately the same rate as the mothers, which is 80 to 85 bpm. Below illustrates the approximate fetal heart rate for weeks 5 to 9, assuming a starting rate of 80

Week 5 starts at 80 and ends at 103 bpm

Week 6 starts at 103 and ends at 126 bpm

Week 7 starts at 126 and ends at 149 bpm

Week 8 starts at 149 and ends at 172 bpm

At week 9 the fetal heartbeat tends to beat within a range of 155 to 195 bpm.

The fetal heart rate will begin to decrease and generally will fall within the range of 120 to 160 bpm by week 12.

So I would say you are fine!

My understanding is that a normal heartbeat for a fetus at 7weeks is 90 to 110.
