In general, the normal range of a child's heartbeat: 80 140 beats per minute within 1 year of age; 1 6 years old 80 120 times min; Over 6 years old 60 100 times min. However, the above frequency should be in a quiet state, if the child is active or participates in physical activity, the heartbeat can increase significantly.

The general heartbeat is related to the age of the person and the heart; The average heartbeat of a normal person is 72 per minute; Breaths are about 23 breaths; In a calm state, the respiratory rate is generally 1 5 to 1 4 of the heartbeat, and even lower during sleep. In the case of hypoxia, strenuous exercise, etc., the body automatically compensates, breathing and heartbeat are increased, the heartbeat can reach more than 140, and the breathing is generally about 30.

I don't know my height and weight, but my heart rate for low- to medium-intensity exercise is 127 minutes to 169 minutes based on standard height and weight.

Generally, the heart rate of normal people is 60-100 times, and the heart rate will be related to the individual's gender, age, diet, mood, etc., and it is generally normal within this range, and the normal breathing is 18-20 times a minute.

It varies from person to person and cannot be generalized. In general, the heart beats 60-65 minutes and the breath is 15-20 minutes. After exercise, the heart rate and respiratory rate increase depending on the degree of striency.

About 60 times is considered normal.

Analysis:

The normal values of heart rate and breathing for children of all ages are as follows:

Newborn breaths: 40-50 beats Pulse: 120-140 breaths Under 1 year of age:

30-40 beats Pulse: 110-130 breaths 2-3 years old: 25-30 pulses

100-120 breaths at 4-7 years old: 20-25 breaths at 8-12 years old

18-20 beats: 70-90 beats.

Guidance: Changes in heart rate are also related to a variety of factors such as eating, exercising, mood, sleep, and fever. A fast heart rate at rest makes sense. After exercising, or being too nervous, the fever will be a little higher than normal.
