Heart beats per minute (BPM). The heart can change its output by increasing its stroke volume or its cardiac rate, where the latter is the most effective and most efficient method. Heart rate varies widely with age, sex, environmental stress, state of health, etc. Therefore, the term "normal" heart rate is meaningless. However, ratio of working cardiac rate over resting cardiac rate is one of the measures of work tolerance and work stress.
