2. Heartbeat, as the name suggests, is the beating of the heart. The right atrium receives venous blood throughout the body, which is pumped out from the pulmonary artery through the right ventricle, and the pulmonary artery flows venous blood at this time, which becomes oxygen-rich arterial blood through the gas exchange in the lungs, which is sent from the pulmonary vein to the left atrium, and then pumped to various tissues and organs of the body through the aorta of the left ventricle to meet the needs of its normal physiological activities.

A normal heart rate should be in the range of 70 to 90 beats in an 8-year-old child, sinus bradycardia should be considered below 60 beats, and sinus tachycardia should be considered if it is more than 110 beats. Intense crying can cause an increased heart rate, which should be a physiological phenomenon. It is not normal for the heart rate to increase or slow down, and the cause needs to be found.

Fever in children often causes a rapid heart rate, which can increase by 10 15 beats for every 1 increase in body temperature. If the heart rate increases significantly and does not return to the normal range during quiet or sleep, it often indicates that the child may have a heart disease, especially when the child is pale, refuses to eat, has night sweats, or is irritable, or if the older child feels suffocated and has chest fluid and is stuffy.
