Pulse is the palpable arterial pulse on the surface of human body.

Heart rate refers to the number of heartbeats per minute of normal people in a quiet state, also known as quiet heart rate, which is generally 60 ~ 100 beats per minute, and may vary among individuals due to age, gender or other physiological factors.

Pulse rate refers to the frequency of arterial pulsation. Pulse rate is influenced by age, sex, exercise and mood.

2. Different times

The pulse and heartbeat of a normal person are the same. Normal adults 60 ~ 100 times per minute, often 70 ~ 80 times per minute, with an average of about 72 times per minute. Older people are slower, 55 to 60 times per minute. Pulse rate is affected by age and sex. Fetal pulse rate is1160 beats per minute, infant pulse rate is 120- 140 beats per minute, and infant pulse rate is 90- 100.

When the heart rate is quiet, the normal heart rate of adults is 60 ~ 100 beats/min, and the ideal heart rate should be 55 ~ 70 beats/min (athletes' heart rate is slower than that of ordinary adults, generally about 50 beats/min).

An adult's pulse rate exceeding 100 beats per minute is called tachycardia, and below 60 beats per minute is called bradycardia.

Extended data:

The pulse rate of normal people is regular, and there will be no phenomenon of different pulse intervals. The pulse condition of normal people is equal in strength, and there will be no alternation between strength and weakness.

In addition, exercise and emotional excitement will speed up the pulse, while rest and sleep will slow it down. Adult pulse rate exceeds 100 times per minute, which is called tachycardia; 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. Traditional Chinese medicine regards pulse as the main method to diagnose and treat diseases.

During the cardiac cycle, due to the alternation of ventricular contraction and relaxation, blood vessels periodically expand and return to the pulse.

The condition is critical, especially the pulse number and frequency before death will change obviously. The change of pulse is also one of the bases for doctors to diagnose patients.

Note: Patients with pump artificial heart have no pulse.

1, tachycardia

When adults are at rest, the heart rate exceeds 100 beats/min (generally not more than 160 beats/min), which is called sinus tachycardia. It is common after excitement, excitement, smoking, drinking or drinking strong tea or coffee, or under pathological conditions such as infection, fever, shock, anemia, hypoxia, hyperthyroidism, heart failure, or when atropine is used.

2, bradycardia

When the adult's heart rate is lower than 60 beats/min (generally more than 45 beats/min), it is called sinus bradycardia, which can be seen in healthy people and athletes who have been engaged in heavy physical labor for a long time; Or in hypothyroidism, intracranial hypertension, obstructive jaundice and excessive digitalis, quinidine or propranolol.

Sick sinus syndrome and atrioventricular block should be considered if the heart rate is lower than 40 beats/min. If the pulse intensity is uneven and the pulse rate is less than the heart rate, atrial fibrillation should be considered.

3. Correct treatment of sinus bradycardia.

Many people will have sinus bradycardia with arrhythmia, which is normal for most people, so don't worry too much. Sinus bradycardia refers to a person whose heart rate is lower than 60 beats/min. Whether this symptom will appear or not is related to the frequency of bradycardia and the causes of bradycardia. In a quiet state, if the adult's heart rate is between 50 and 60 beats per minute, there will generally be no obvious symptoms.

Especially for some well-trained athletes and people who have been engaged in manual labor for a long time, even if the heart rate is about 40 beats/minute in a quiet state, there will be no obvious symptoms.

However, if the average person's heart rate is between 40 and 50 beats per minute, there will be symptoms such as chest tightness, fatigue and dizziness. If the heart rate drops to 35 to 40 beats/min, hemodynamic changes will occur, which will affect the blood supply to the heart and brain organs, leading to chest pain, dizziness, syncope and even sudden death.
