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

Extended data

Heart rate changes are closely related to heart disease. If the heart rate is greater than 160 beats/min, or less than 40 beats/min, it is more common in patients with heart disease. As usual, accompanied by palpitation, chest tightness and other discomfort. It should be examined in detail as soon as possible in order to treat the cause.

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.
