The criteria for a normal pulse include a pulse that is normal in terms of rate, rhythm, and intensity.
Pulse is the vibration caused by the blood hitting the walls of the blood vessels when the heart beats, and under normal circumstances, the pulse and heart rate remain consistent. The normal range of pulse rate is 60-100 beats per minute in adults and slightly faster in children, mostly above 100 beats per minute.
A normal pulse has a regular rhythm and is synchronized with the heartbeat. When there are pathological changes, such as atrial fibrillation, there may be a short pulse and an absolutely irregular pulse rhythm.
Normally, the intensity of the pulse is moderately strong. When there is a decrease in cardiac output, as in the case of heart failure, shock, etc., the pulse can become weak or not palpable. In the case of atrial fibrillation, the pulse may appear to be of variable strength.
When an abnormal pulse occurs, it is recommended to seek prompt medical attention and standardized treatment.
