The pulse is represented by the letter p.

First of all, pulse

Pulse condition generally refers to pulse rate. Pulse rate refers to the frequency of arterial pulsation, which is generally measured by the number of pulses per minute. Pulse rate is a common clinical vital sign index, which is influenced by many factors, such as age, gender, mood, disease and so on. An adult's pulse rate exceeding 100 beats per minute is called tachycardia, and below 60 beats per minute is called bradycardia.

When the patient has heart disease, endocrine disease, anemia, infection, fever, hypoglycemia and shock, the pulse rate may be abnormal. Pulse belongs to the palpable arterial pulse on the human body surface, generally referring to the pulse of small blood vessels in the wrist, which can indirectly reflect the heartbeat. If the pulse is obviously abnormal, you should go to the cardiovascular department of the hospital in time and take corresponding treatment measures under the guidance of a doctor so as not to affect your health.

After the heart contracts, a large amount of blood will be ejected, some blood will flow out through the aorta and then be shunted, and some blood will continue to flow in the small and medium-sized arteries, resulting in blood flow shock waves. This shock wave can be felt in the superficial arteries of the body, which is the pulse. Because the pulse frequency of arterial blood changes little after shunt, the pulse frequency is almost equal to the heart pulse frequency, so normal people often use pulse to reflect the heartbeat.

Second, the normal value

The pulse and heartbeat of a normal person are the same. The pulse frequency is influenced by age and sex, with infants 120- 140 beats per minute, children's 90- 100 beats per minute, school-age children's 80-90 beats per minute and adults' 70-80 beats per minute. In addition, exercise and emotional excitement will speed up the pulse, while rest and sleep will slow it down.

Adult pulse rate greater than 100 beats per minute is called tachycardia, and less than 60 beats per minute is called bradycardia. There are many diseases in clinic, especially heart disease, which will change the pulse. Therefore, pulse measurement is an essential examination item for patients. Chinese medicine even regards pulse-taking as the main method for diagnosing and treating diseases.
