Irregular Toddler Heart Rate Strange Heartbeat?

Strange heartbeat? - irregular toddler heart rate

earlier in the evening, my 2 years old son ran into the garden and has its head, the blow was big and blowing, that I was the local NHS walk in the middle. while being examined by the nurse said she had a heart attack "strange", because after 20 shots, which is a double blow. She said he had nothing to fear, but take the documentation, on Tuesday to check there. However, this is worrying, because my partner had a heart attack just over a year at a young age and I believe my son is in the same way! Can anyone me some information about heart rhythm disorders in young children?
