Generally refers to the number of heartbeats per minute. The resting heart rate of normal adults has significant individual differences, with an average of about 75 beats/min (between 60- 100 beats/min). Heart rate changes 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.
If the heartbeat is 50 times per minute, it is considered bradycardia. It doesn't matter much if you are an athlete. The number of heartbeats exceeds 100 per minute, which is called tachycardia.
. Sometimes taking antihistamine cold medicine, coffee, tea, amphetamines or nervousness, anemia, fever, hyperthyroidism or other heart diseases can cause tachycardia. Patients with persistent tachycardia should continue to be followed up.
