Final answer:
The normal heart rate for an infant (1-12 months) is 120-160 beats per minute.
Step-by-step explanation:
The normal heart rate for an infant (1-12 months) is 120-160 beats per minute (bpm).
An infant's heart rate is faster than that of older children and adults due to the rapid growth and development of their cardiovascular system. As the child gets older, their heart rate gradually decreases and becomes similar to that of adults.
