What is the normal heart rate range for an infant?

The normal heart rate range for an infant is typically between 100 and 180 beats per minute. This elevated rate reflects the infant's higher metabolic demands and smaller size compared to older children and adults. During the first year of life, an infant's body is developing rapidly, and higher heart rates are necessary to support growth and maintain blood circulation effectively.

The heart rate will gradually decrease as the child matures, reaching a more adult-like range as they grow older. Understanding this normal range is crucial for first responders and healthcare providers when assessing the health and vital signs of an infant, as deviations from this norm could indicate a medical issue that requires immediate attention.
