According to the Mayo Clinic, the normal resting heart rate for humans is between 60 and 100 beats per minute. A heart rate is found by taking a pulse for 15 seconds and multiplying the result by four.
The Mayo Clinic points out that, although the normal heart rate lies within a range, the lower end typically signifies good cardiovascular condition and an efficiently pumping heart. Heart rate fluctuates during the day in response to many types of stimuli, such as activity, air temperature, body position, emotional state and medication. A heart rate that is outside the normal range sometimes indicates a health problem, and medical personnel should be consulted. Having a heart rate above 100 is called tachycardia, while having one below 60 is referred to as bradycardia.
