My Kid Has Got Irregular Heart Beats, He Is Very

My kid has got irregular heart beats, he is very much normal. As father I doubt that he is not growing well . He had enteric fever 6 years back. I m a doctor. Not done any investigations fearing that something serious will come. As such he is playing cricket very hard. Still that irregular heartbeats are there. Guide me but don't ask me to meet a cardiologist.
