Fortune-telling heart rate _ divining heartbeat

The heart rate is more or less normal, about 0/00 beats per minute/kloc or faster.

1. There are significant individual differences in resting heart rate of normal adults, with an average of about 75 beats/min (between 60- 100 beats/min). Heart rate may vary with age, sex and other physiological conditions. The newborn's heart rate is very fast, reaching 130 beats/min or more. Among adults, women's heart rate is generally slightly faster than that of men.

The same person's heart rate slows down when he is quiet or sleeping, and increases when he is exercising or excited. Under the influence of some drugs or neurohumoral factors, his heart rate will increase. People who often engage in manual labor and physical exercise usually have a slow heart rate. In recent years, a large sample study of healthy people in China found that the normal range of resting heart rate in China is 50-95 beats/min for men and 55-95 beats/min for women. Therefore, the heart rate varies with age, sex and health.

What is the normal range of human heart rate? What is the standard heart rate?

2. The heart rate of healthy adults is 60 ~ 100 beats/min, most of them are 60 ~ 80 beats/min, and women are slightly faster; Children under 3 years old often exceed 100 times/minute; Older people are slow to respond. Adult heart rate exceeds 100 beats per minute (generally not more than

160 times/minute) or above infants.

150 beats/min is called sinus tachycardia. Common in normal people after exercise, excited, excited, smoking, drinking, drinking strong tea. It can also be seen in fever, shock, anemia, hyperthyroidism, heart failure and the application of atropine, adrenaline and ephedrine. If the heart rate is at

160 ~ 220 beats/min, often called paroxysmal tachycardia. Heart rate lower than 60 beats/min (generally higher than 40 beats/min) is called sinus bradycardia.

It can be seen in athletes who have been engaged in heavy physical labor for a long time; Pathological manifestations are hypothyroidism, increased intracranial pressure, obstructive jaundice, digitalis, quinidine or propranolol overdose or poisoning. If the heart rate is lower than 40 beats/min, atrioventricular block should be considered. Heart rate is too fast to exceed 160 beats/min, or less than 40 beats/min, which is more common in patients with heart disease. Patients often have palpitations, chest tightness and precordial discomfort, so detailed examination should be carried out as soon as possible to treat the cause.

Every time the heart contracts, the blood output from the ventricle to the artery is called stroke output, and the blood output from the heart every minute is called stroke output. Under normal conditions, the stroke output is 70 ml, and if the heart rate is calculated at 75 beats per minute, the stroke output is about 5250 ml. Cardiac output is an index to measure the working ability of the heart.
