A normal person’s heart rate is about 60 to 100 beats per minute, with a resting heart rate of 50 to 95 beats per minute for domestic males and 55 to 95 beats per minute for domestic females. Heart rate can also be affected by age. For younger adolescents and children, the heart rate is faster, perhaps 100 to 120 beats per minute, and for infants and toddlers even 120 to 150 beats per minute. For older adults and athletes, the heart rate is slower and may average 50 to 60 beats per minute, which is within the normal range. If the heart rate is greater than 100 beats per minute, it is called tachycardia, and if it is less than 60 beats per minute, it is called bradycardia. However, some athletes who enjoy sports or fitness may have a slightly slower heart rate of about 50-60 beats per minute, which is usually not accompanied by clinical symptoms and does not require treatment. If abnormal heart rate occurs, it is recommended to consult a doctor in time, with the help of a doctor to clarify the cause, targeted treatment or therapy.
