Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: 6F, 50lbs, 3 11 Melatonin supplement at night (.03mg), probiotics Medical history (not sure if its relevant) - she was diagnosed with neutropenia when she was 2. Saw hematology for a period of time because they suspected cyclic neutropenia (her levels fluctuated over 6 weeks of finger pokes), but since she was healthy, and didnt seem to have other symptoms, they did not want to do a spinal tap. The few times shes had bloodwork since, her levels have been within normal range. So possible neutropenia of childhood. I recently invested in a personal ECG device (Wellue Pulsebit EX) for me to keep track of my own arrhythmias. But I used it on her, and got irregular heartbeat results. The AI analysis describes it as PACs/supraventricular tachycardia, though Ive tested her 8 times in the last 2 days at differing times and four of them have come up as this and one came up with PVCs (so 5 out of 8 were irregular). I am curious if this is something I should speak with her doctor about, or is this because the device is not taking her young age into consideration. I looked up PACs in young children and while it says some are normal, if they are more frequent then they should be investigated further. Im trying not to worry myself silly, but I would definitely appreciate any insight. Thank you! Im going to comment with a photo of one of the readings, since I cant figure out how to add a photo and text to this post.. ### Response: These are not approved for children. Do not use them on her.Children have very different hearts than adults. Their heart rates are generally higher. It is generally not recommended to routinely screen asymptomatic children with monitoring devices like this. The thought process is that it generally leads to a lot of anxiety (as you've probably noticed) and unnecessary testing without actually saving very many lives. If she passes out, bring her to a doctor to have her assessed by machines designed for interpretation of children's hearts..
