What is the normal heart rate for infants aged 0-3 months?

The normal heart rate for infants aged 0-3 months typically ranges from 80 to 160 beats per minute (BPM). During this early stage of life, infants require a higher heart rate to support their rapid growth and high metabolic demands.

This range accounts for various factors such as physiological changes, activity levels, and the naturally higher heart rates in younger children compared to adults. Infants in this age group are often more active, which can lead to momentary increases in heart rate, but the overall normal range remains consistent.

Understanding this normal range is important for assessing an infant's health and identifying potential issues such as bradycardia (a slower than normal heart rate) or tachycardia (a faster than normal heart rate), both of which could indicate underlying health concerns.
