What is the practical value of the ability to count the pulse?

Pulse counting helps to determine the state of a person, it can tell about some of his functions. For example, knowing that a healthy person has a heart rate of about 80 per minute, one can conclude about his health. A more frequent pulse occurs with low pressure, fatigue, nervous strain, if a person is injured and feels pain. Also, a frequent pulse occurs at a high body temperature: for example, at a temperature of 37.6, the pulse will become more frequent by 10 beats. A rare pulse occurs in athletes, people who regularly engage in physical activity. But there is also a rare pulse, which indicates a disease: if the heart rate is less than 55 per minute.
