Question
Why does a child have a rapid heartbeat?
Answer
Based on your description, a child’s rapid heartbeat may be due to viral infections, excessive exercise, or insufficient rest, among other reasons. It is recommended that you take your child to the hospital for a blood test and cardiac enzymes to determine if there is an issue. If there is no issue, it may be due to recent excessive exercise or insufficient rest. It is suggested that the child get adequate rest and observe if there is any improvement.
