<s>[INST] hi, i recently purchased a blood pressure monitor for myself and tested my 10 year old son with it,i was very worried when it showed up as detecting a irregular heart beat ,could the blood pressure monitor be wrong because its meant to be for adults,it came up with this reading almost every time.thankyou. [/INST] Hi. I understand your concern. All the automatic blood pressure monitors are pre-programmed and just an interpretation in that doesn't confirm or rule out an underlying problem. Moreover, since you have mentioned that it's an adult BP cuff, errors are also possible. I would advise you to get your son examined by a Pediatrician and get certified. Any further questions, I would be pleased to help you.  Chat Doctor. S. Sri Vichy Chennai </s>
