Is this normal for a 5 y/o!!!!!

My 5 year old son keeps complaining that his chest hurts. So me being the corpsman that i am i took my stethascope and listened to his chest and heart and i am a little lost. His heart beats were uneven, when he would breath in they would become tachy then when he would breath out they would stop then become very brady. I understand childrens heartbeats vary from adults, but if this was one of my patients i would have done an EKG to see if there were any abnormalities and then transported them to the nearest ER. Am i just overthinking this or should i get him checked out? I feel silly asking all this but i just couldn't find anything on this when i researched it! Thank you in advance!
We cannot give medical advice. Take him to the doctor or ER thank you!Per terms of use

We can't give medical advice. If you have any concerns then call your childs pedi or take him to the ER.

Sounds kind of like sinus arrythmia to me, which is totally normal in kids. Probably a good idea to take him in for a check up though. He shouldn't be having chest pain.Here is some info on sinus arrythmia. http://en.wikipedia.org/wiki/Sinus_arrhythmia

Get him checked out !!!

Above posters are correct: please have him seen by his pediatrician. Thanks.
