My five year old daughter comes to me quite frequently complaining of rapid heartbeat, her legs are shaking uncontrollably and she has a lot of leg pain....I m not an over reacting mom as my 8 year old was born with Pierre Robin Sequence and we have been through everything you can imagine with him...she has always seemed quite healthy. Any suggestion
Hi...rapid heart beat and that too from a 5-year-old who cannot just like that lie about it should not be ignored. It could be a supraventricular tachycardia or any other rhythm abnormality. I suggest you take her to the nearest emergency at the earliest. Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
