What is the normal heart rate range for an infant?

The normal heart rate range for an infant typically falls between 120 to 150 beats per minute. This elevated heart rate is a normal physiological response in infants due to their smaller size and greater metabolic demand compared to adults. Infants require a steadier blood flow to meet their body's needs, contributing to this heart rate range.

Heart rates outside this range, particularly those that are significantly lower or higher, can indicate distress or underlying medical issues. For instance, a heart rate that is persistently below 120 may suggest bradycardia, whereas a rate exceeding 150 could indicate tachycardia. Understanding the appropriate heart rate range is crucial for caregivers and medical professionals when assessing an infant's health and determining if immediate intervention is necessary.
