*”heart rate” is the speed of the ‘heartbeat’ measured by the ‘# of contractions of the heart per minute’ (‘bpm’)*
.
(the ‘heart rate’ can vary according to the body’s physical needs, including the need to absorb ‘oxygen’ + excrete ‘carbon dioxide’)
(it is usually equal or close to the ‘pulse’ measured at any peripheral point)
(activities that can provoke change include ‘physical exercise’, ‘sleep’, ‘anxiety’, ‘stress’, ‘illness’, and ‘ingestion of drugs’)
(many texts cite the ‘normal resting adult human heart rate’ range from 60–100 bpm)
(‘tachycardia’ is a ‘fast heart rate’, defined as ‘above 100 bpm at rest’)
(‘bradycardia’ is a ‘slow heart rate’, defined as ‘below 60 bpm at rest’)
(several studies, as well as expert consensus indicates that the ‘normal resting adult heart rate’ is probably closer to a range between 50–90 bpm)
(during sleep a ‘slow heartbeat’ with rates around 40–50 bpm is common and is considered ‘normal’)
(when the ‘heart’ is not beating in a regular pattern, this is referred to as an ‘arrhythmia’)
(abnormalities of ‘heart rate’ sometimes indicate ‘disease’)
