Why is taking a carotid pulse for 15 seconds a problem?
Pulse is intended to be a count per minute. By only taking it for 15 seconds, then any error you make is multiplied by a factor of 4. If you count 15 beats and multiply by 4, you get 60. But if you missed 2 of the beats, then the actual count should've been 68. However, getting a pulse over a full minute can make a patient nervous and impatient - sometimes causing the pulse to go up. So 15 seconds is the normal wait time unless there is a reason to suspect a problem. Either from other symptoms or a bad result. For example, if the patient had a very high blood pressure and a low pulse, chances are, one of those two test results are wrong. So a recheck with a longer time frame would be suggested.
What is the meaning of beat as an element of rhythm?
A beat is a regularly recurring pulse or stress point in the music, over which the melodic rhythm is overlaid. The essence of rhythmic music is a pulse which recurs at regular intervals, usually interspersed with lesser pulses which equally subdivide the time between the greater pulses. A march rhythm might be set up by having a pulse followed .5 seconds later with a lesser pulse, then the greater pulse .5 seconds later and so on. Each of these greater and lesser pulses is called a beat. Not all music emphasizes the beats; in some, the placement of the beats must be implied from the rhythm of the melody or melodies.
