    Default Heartbeat 111bpm @7wks. Low?

    After searching through some forums I have noticed others that have had ultra sounds at or around 7 weeks & the baby's heartbeat was 150-170bpm. My scan at 7weeks showed a HB of only 111bpm. Although the report said it was normal, I am a little concerned. Can anyone shed some light on this? Should I be worried?

    Georgi, I wrote this down in a thread last year. Hope it helps

    Week 5 - heartbeat 80 - 103 bpm
    Week 6 - 103-126
    Week 7 - 126 - 149
    Week 8 - 149 - 172
    Week 9 - 155 - 195

    I don't think there would be anything to worry about, everyone is going to be different.
    Congrats on your pregnancy

    In the ning nang nong...


    This information is from the American Pregnancy Association website:

    Week 7 Gestational Age (Fetal Age 5 weeks)
    Generally from 6-7 weeks is the time when a heartbeat can be detected and viability can be assessed. A normal heartbeat at 6-7 weeks would be 90-110 beats per minute. The presence of an embryonic heartbeat is an assuring sign of the health of the pregnancy. Once a heartbeat is detected, the chance of the pregnancy continuing ranges from 70-90% dependent on what type of ultrasound is used. If the embryo is less than 5mm CRL, it is possible for it to be healthy without showing a heartbeat, though a follow up scan in 5-7 days should show cardiac activity.
    Hope that helps ease your anxiety a little. If I see anything else, I'll post it. Lots of love and

    Hiya Georgi

    We don't stop worrying hey - all is different - my friend's scan at same time was 117 so when I told her mine was 154 she was amazed - she is now 23 weeks and all is perfectly fine

    Kerry, I loved your post about if heartbeat detected percentage of likely to continue 70 - 90% - reassuring. last time I had u/s at 10.5 wks and had a heartbeat but 2 weeks later, bubs had become an angel at 11 weeks - no rhyme or reason. I did have a severe case of food poisoning which at the time docs said don't worry, but it is a bacterial infection, not viral like the tummy bugs that are going around .... so opinion was inconclusive.

    But with the figures, I have more confidence that this one will go smoothly

    Georgi, take care hun - it is hard not to compare with others - I need to practice what I preach too LOL

    The 'normal' heartbeat is between 110 and 160. If your baby is sleeping it is not unusual to be a little lower than 110 and if your baby is active it can be higher than 160. At 7 weeks the heartbea5t is often on the lower side of 'normal'
