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!
