Can anyone help me with the following: I had an u/s at 6wks 3days and there was a heartbeat of 110 beats per min? My dr mentioned that this may be a bit slow. I cannot find much info on how fast it should be. This is my first pregnancy and all very unknown!

when it first starts to beat its usually suppose to be between 120-160. Anything under that range is usually a sign that somthing may be wrong. Its best to get a reading at or around 8 weeks b/c then the hearts been beating for awhile and it picks up some. Your dr. might advise you to come back in 2 weeks to ck it again. When i was 6w1d the hb was 124. at 10weeks it was bw 150's and 160's. now at 12.5 weeks along i'll find out on friday what the hb is now.

hi there. all heart rates are different. especially if you are a smoker. an adult heart beat averages around a 100. I was always told that once it goes under 120 at ANY time during preganancy it raises eyebrows. Does not mean though that there is neccesarily a problem. baby is new going through more changes than anything. i hope all goes well for you.

My second child had a heartbeat of 118 at 6 weeks. Everything was fine and she is now 3!

I had my 1st u/s done at 6 wks 3 days too and my baby's heartbeat was 123 bpm. And they said its normal...Not sure though about 110 bpm. Did you talk to your Dr. about it?

Thanks so much for all your responses. I have another ultrasound in 2 days and hope to find out if there has been any changes. I had major bleeding the day before the last ultrasound and there is a chance that i may have a second pregnancy that is ectopic, but it could also be a cyst. The unknown is scary but just really want it all to be sorted. The Dr said it was a bit of a worry with the heartbeat but he also said that the reading may have not been accurate. Who knows...

The sonographer who performed my first ultrasound at 6 weeks said they want to make sure it is over 100. You probably just got the u/s a little soon.
