Hi there, my 5 year old daughter has recently been saying her chest hurts when she plays tag in gym. She is a very healthy weight, if anything could stand to gain some weight, but she is very active in dance and gymnastics. I have noticed in the past she does have rapid heart rate at times and irregular. Is it normal for a 5 year old to have irregular heart rate? At times it is very bounding.
Absolutely it is abnormal if irregular. You should immediately consult your family physician or pediatric cardiologist.
