Heart rate refers to the number of times the heart beats per unit of time. The normal healthy adult heart rate is 60-100 beats per minute in a quiet state, and the heart rate of infants and young children is higher than that of adults.
In normal healthy adults, a heart rate of more than 100 beats per minute in a quiet state is called tachycardia, while a heart rate of less than 60 beats per minute is called bradycardia. Special attention should be paid to the slow heart rate of the elderly, the fast heart rate of women, the heart rate of children younger than 3 years old is more than 100 beats/min, and the heart rate of infants and young children is more than 150 beats/min before it is called tachycardia.
Tachycardia and bradycardia can be transient or persistent, and can be caused by a variety of physiologic and pathologic factors. For example, physiological bradycardia in athletes, tachycardia can be caused by staying up late at night, smoking and drinking alcohol, and coronary heart disease, valvular disease and other cardiovascular diseases can lead to tachycardia or bradycardia.
If you find abnormal heart rate, please consult a regular hospital in time.
