I went in for a second ultrasound at 8 weeks and was told the fetus was measuring 6 weeks with a low heart rate of 86. What chance of miscarriage?

A precise number. .: .... or chance of miscarriage can not be estimated from these reports, but you are right to be concerned about a low heart rate and small fetal size. Both of these ultrasound associated findings can be interpreted as risks for impending miscarriage. I understand waiting and hoping is difficult...I do hope this is just a temporary blip and all will be well. Stay in close touch with your provider. ...Read more

Parent had pacemaker put in due to low heart rate (30's-40's). Had high BP and is overweight. What are the likely causes of decreased heart rate?

Slow heart rate: Just answered this earlier. We had no definite cause to this. The sinus node, or the heart pacer is just simply slow in firing, could have been from previous ischemia but we can't say for certain. It is not a common condition but we see it enough and yes more in the elderly, so the ischemic theory probably is true. ...Read more

What to do if I have pacemaker for low heart rate today I'm runnin high 90's BP 133/ 91?

Pacemaker: The pacemaker is likely programmed to stimulate your heart if your intrinsic rate falls below a programmed rate like 60 or 70 beats a minute. If your heart is going 90 on its own, the pacer is just monitoring to see how fast the heart is going and will 'kick in' if your heart slows to under the programmed rate. ...Read more
