<unk>  is a term used to describe the frequency of the cardiac cycle. It is considered one of the four vital signs. Usually it is calculated as the number of contractions (heart beats) of the heart in one minute and expressed as "beats per minute" (bpm). See "Heart" for information on embryofetal<unk> s.
When resting, the average adult human heart beats at about 70 bpm (males) and 75 bpm (females); however, this<unk>  varies among people and can be significantly lower in athletes. The infant/neonatal<unk>  of heartbeat is around 130-150 bpm, the toddler's about 100–130 bpm, the older child's about 90–110 bpm, and the adolescent's about 80–100 bpm.
The pulse is the most commonly used method of measuring the<unk> . This method may be inaccurate in cases of low cardiac output, as happens in some arrhythmias, where the<unk>  may be considerably higher than the pulse<unk> .
Listening to heart sounds using a stethescope, a process known as Auscultation, is a more accurate method of measuring the<unk> .
