It is not bps, but bpm - beats per minute. Heart hardly beats a little more than once every second. So there is no point in counting beats per second. In most persons, the number of heart beats and number of pulses will be the same. In rare situations like atrial fibrillation
, heart rate
will be more than pulse rate and there will be something which is called as a "pulse deficit". This is because some beats are not forceful enough to open the aortic valve
and does not produce a pulse.
