Pulse is the rhythm of our heart beating and blood flowing. I believe everyone has felt it in their lives. So do you know what the normal range of pulse is? Normal range Pulse is the beating of the pulse, and the frequency of the pulse is the pulse rate. A normal person's pulse is consistent with his heartbeat. The normal adult pulse rate is 60 to 100 times per minute, usually 70 to 80 times per minute, and the average is about 72 times per minute. The heart rate in the elderly is slower, at 55 to 60 beats per minute. A normal person's pulse rate is regular, and the pulse intervals do not vary in length. A normal person's pulse is of equal strength and does not alternate between strong and weak. The pulse frequency is affected by age and gender. The fetus beats 110-160 times per minute, the infant beats 120-140 times per minute, the toddler beats 90-100 times per minute, and the school-age child beats 80-90 times per minute. In addition, exercise and emotional excitement can increase the pulse, while rest and sleep can slow down the pulse. An adult pulse rate of more than 100 beats per minute is called tachycardia; a pulse rate of less than 60 beats per minute is called bradycardia. There are many clinical diseases, especially heart disease, that can cause pulse changes. Therefore, measuring the patient's pulse is an indispensable examination item. Traditional Chinese medicine uses palpation as the main method for diagnosing and treating the disease. During the cardiac cycle, the blood vessels undergo periodic expansion and return of pulsation due to the alternation of ventricular contraction and relaxation. When the patient is critical, especially before death, the pulse frequency and rate will change significantly. Changes in pulse are also one of the bases for doctors to diagnose patients. Clinical significance of pulse Abnormal results 1. Pulse rate In addition to the speed of the pulse rate, you should also check whether the pulse rate is consistent with the heart rate. In some arrhythmias such as atrial fibrillation or frequent premature contractions, the pulse rate may be less than the heart rate because the stroke volume of some cardiac contractions is low and insufficient to cause peripheral arterial pulsation. 2. Pulse rhythm The rhythm of the pulse reflects the rhythm of the heart. The pulse rhythm of patients with various arrhythmias may be affected. For example, the pulse rhythm of patients with atrial fibrillation is absolutely irregular. The pulse strength varies. and pulse rate is less than heart rate. The latter is called pulse deficiency; those with premature contractions in bigeminy or tripegemny may form bigeminy or tripegemny; those with second-degree atrioventricular block may have pulse omission, called dropped pulse, etc. 3. Tension and arterial wall condition After compressing the radial artery, although the distal finger cannot feel the arterial pulsation, the existence of strip-like arteries can be felt, and they are hard and inelastic, like cords, tortuosity or nodules, indicating arteriosclerosis. 4. Strength and Weakness A weakened pulse with low amplitude is caused by low cardiac volume, low pulse pressure and increased peripheral resistance, and is seen in heart failure, aortic valve stenosis and shock. Conclusion: Through the introduction above, I believe everyone has a more comprehensive understanding of the normal range of pulse. The pulse usually changes. When we do different things, the pulse is also different. I hope the above article can help everyone. |
