Disease description:

Today, while holding my child, I suddenly noticed that his heartbeat was very rapid. I haven’t taken him for a medical evaluation yet. I’d like to ask: Is a rapid heartbeat in children considered normal? What should I watch out for?

Hello, an abnormally rapid heartbeat in a child is not normal and requires evaluation—specifically, how fast the heart rate is. Generally, a resting heart rate between 60 and 100 beats per minute is considered normal. However, transient tachycardia may occur when a child is unwell, crying, or has engaged in vigorous physical activity. Please continue to observe your child for any additional abnormal symptoms, and consider consulting a healthcare provider for further evaluation and appropriate diagnostic tests. I hope this information is helpful. Wishing you and your child good health.
