hello mai apne bacche ka heart rate cheak kar rahi hu oximeter se toh jab wo so Raha h toh bhi heart rate stable nhi ho raha h 5-10 sec me badh or kam ho raha h there is any problem or it's normal?????

A. During the sleep time the heart rate can vary so I don’t think so it’s a problem till the variation is not very high if it is only like one or two times over up and down then it is normal but if it is a vast difference then you should check with your doctor
