A normal person’s heartbeat is very regular, at 60 to 100 beats per minute. If the pulse is felt to be beating irregularly, there may be an arrhythmia, and many changes in the condition can be seen from the speed, rhythm, and changes in the strength of the pulse. The number of pulses and the number of heartbeats are the same in normal people (with the exception of patients with arrhythmias). Therefore, the pulse rate can be measured to obtain a value for the heart rate. You must stop exercising, consuming coffee, alcohol and smoking one hour before the measurement and rest for at least 5 minutes before the measurement. While lying down or sitting, relax your legs, stop talking, and gently press the end of the second, third, and fourth fingers of your right hand against the radial artery (the side of the wrist, anterior and medial to the radial styloid process, where the pulse is taken in traditional Chinese medicine) for 1 minute. If touching the radial artery is not convenient, the pulse can also be measured by touching the temporal artery (in front of the ear screen), the carotid artery (on both sides of the anterior cervical trachea) and the dorsalis pedis artery (in the middle of the dorsalis pedis). Measuring the pulse of the elderly is an important method of observing changes in their condition and an easy means of self-testing their health, and every elderly person should learn how to measure their own pulse. If you feel a discontinuous pulse with your own hand, have long intervals, and feel uncomfortable in your heart, feel a strong heartbeat and then a pause, or have a heartbeat that feels like a sudden drop in an elevator, this may be a premature beat or atrioventricular block. Premature beats are one of the most common forms of arrhythmia and can occur in both healthy people and those with cardiovascular disease. If they occur less frequently or occasionally per minute, they do not have a significant impact on the function of the heart. One normal heartbeat followed by one premature beat is called duplex rhythm, two premature beats followed by one normal heartbeat or one premature beat followed by two normal beats is called triplet rhythm, and three or more consecutive premature ventricular beats are called short-onset ventricular tachycardia. Second, triplets or ventricular tachycardia are both more serious arrhythmias. Depending on the site of occurrence of premature beats, they can be classified as atrial, atrioventricular junctional and ventricular premature beats, with ventricular premature beats being the most common. Premature beats can occur in healthy people, especially in young people, when they are stressed, overtired, smoking, drinking alcohol, drinking strong tea or coffee, or even when they have a fever. Of course, premature contractions are most common in patients with various heart diseases, such as coronary heart disease, wind heart disease, myocarditis, cardiomyopathy, and so on. Certain drugs and infectious diseases can also cause premature beats. If your pulse exceeds 100 beats per minute at rest, it is called tachycardia, which means that your heart rate is too fast. The tachycardia is divided into sinus tachycardia and supraventricular tachycardia, with sinus tachycardia being less severe and supraventricular tachycardia being more severe. The pulse beats extremely irregularly, fast and slow without accuracy, varying in strength and weakness, touching the heartbeat all chaotic, feeling upset, it may be atrial fibrillation, which is also one of the more common arrhythmias, atrial fibrillation is more common in elderly cardiovascular patients, there are fast and slow atrial fibrillation is the most characteristic of “three inconsistencies”, that is, the heartbeat is inconsistent in strength, inconsistent in speed , pulse and heartbeat inconsistency, that is, the heartbeat sometimes can not be transmitted to the pulse, the greatest danger of atrial fibrillation is easy to induce cerebral infarction. If the pulse is below 60 beats per minute, it is considered bradycardia. Sinus bradycardia, seen in normal young people, especially athletes, often exercise heart rate is likely to be slower than normal. However, if the heart rate is below 40 beats/min, it is often accompanied by atrioventricular block, which is a more difficult disease to treat, mostly seen in myocarditis, cardiomyopathy, coronary artery disease, etc. Other people have fast and slow heart rates, more than 100 beats/min when fast and less than 60 beats/min when slow, medically called fast-slow syndrome, which may be the heart’s engine – sinus node problems, more troublesome to treat. We would like to remind you that the above is only a preliminary judgment of the arrhythmia, but the diagnosis needs to be confirmed by an ECG and other tests at the hospital to determine if there is an arrhythmia.
