The normal heart rate range is between 60 to 100 beats per minute, although some individuals, such as athletes, may have a lower normal resting heart rate, according to Mayo Clinic. Children younger than 10 years old can have a higher range of resting heart rate, claims MedlinePlus.
Newborns may have a heart rate range between 70 and 190 beats per minute. An individual's heart rate varies throughout the day depending on physical activity, air temperature and position of the body, notes Mayo Clinic. Heart rate is measured by placing the tips of the index and middle fingers together on the wrist to find the pulse. Each beat is counted over one minute.
Knowing the normal heart rate range is important because a heart that continually beats too slowly, too quickly or irregularly can cause damage to the lungs and brain, asserts the American Heart Association. A resting heart rate faster than 100 beats per minute is a condition called tachycardia, and a resting heart rate slower than 60 beats per minute is called bradycardia. An electrocardiogram, or EKG, can help diagnose arrhythmia. For children with arrhythmia, several different types of surgeries, such as cardiac ablation, are available to attempt to correct the irregular rhythm, states Cleveland Clinic.
