The maximum heart rate (HR max) is the age-related highest number of beats per minute of the heart when reaching a point of exhaustion [28] [29] without severe problems through exercise stress. [30] In general it is loosely estimated as 220 minus one's age. [ 31 ]
For example, a tempo of 60 beats per minute signifies one beat per second, while a tempo of 120 beats per minute is twice as rapid, signifying two beats every second. The note value of a beat will typically be that indicated by the denominator of the time signature. For instance, in 4 4 time, the beat will be a crotchet, or quarter note.
Cardiac output (CO) is the product of the heart rate (HR), i.e. the number of heartbeats per minute (bpm), and the stroke volume (SV), which is the volume of blood pumped from the left ventricle per beat; thus giving the formula: = [3] Values for cardiac output are usually denoted as L/min.

The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...
The most-common arrangement of tempos on a Maelzel metronome begins with 40 beats per minute and increases by 2 BPM: 42 44 46 48 50 52 54 56 58 60, then by 3 BPM: 63 66 69 72, then by 4 BPM: 76 80 84 88 92 96 100 104 108 112 116 120, then by 6 BPM: 126 132 138 144, then by 8 BPM: 152 160 168 176 184 192 200 208.
A typical heart rate is 75 beats per minute (bpm), which means that the cardiac cycle that produces one heartbeat, lasts for less than one second. The cycle requires 0.3 sec in ventricular systole (contraction)—pumping blood to all body systems from the two ventricles; and 0.5 sec in diastole (dilation), re-filling the four chambers of the ...
Cells in the SA node spontaneously depolarize, ultimately resulting in contraction, approximately 100 times per minute. This native rate is constantly modified by the activity of sympathetic and parasympathetic nerve fibers via the autonomic nervous system, so that the average resting heart rate in adult humans is about 70 beats per minute.
