A good pulse rate for an adult at rest ranges from 60 to 100 beats per minute, according to Mayo Clinic. When the heart rate is low while resting, it indicates cardiovascular fitness and a more efficiently functioning heart.
Emotions, body size, body position, athletic training and medications all play parts in the pulse rate of a healthy person at rest. A heart rate that is unusually high or low indicates the possibility of one or more underlying health conditions, explains Mayo Clinic. When a person experiences a consistently high or low pulse rate, he needs to consult a doctor.
