Arrhythmia is the most common clinical heart disease, mainly manifested by a fast or slow heartbeat, or irregular or untidy. For patients who already have arrhythmia disease, they must master the method of self-testing pulse, which is used to initially determine the type or severity of arrhythmia. The following is a brief introduction to the method of self-testing pulse. Place our arm easily on the tabletop, or on your lap, as long as it is convenient to measure. Press your index and middle fingers against the radial artery with a moderate amount of pressure, just enough to feel a pulse beat (see picture below). We can measure for 30 seconds, and then multiply the number of pulse beats by 2, which is the number of pulse beats we have in a minute, usually 60-100 beats/minute for adults. It should be measured in a calm state to better reflect our basal pulse rate. What is the relationship between pulse rate and arrhythmia? 1. If the pulse rate exceeds 100 beats/minute in a quiet state, it is called tachycardia, which means that the heart rate is too fast. If the pulse is lower than 60 beats/minute, it is bradycardia. Healthy people or acute heart attack, myocarditis, heart failure, etc. can appear faster heart rate, tachycardia is divided into sinus tachycardia and supraventricular tachycardia, the former is milder, the latter is more serious. Slow heartbeat can be seen in normal young people, especially athletes, and it is possible to have a slower than normal heart rate with regular exercise. However, if the heart rate is below 40 beats per minute, it is often associated with atrioventricular block, which is a difficult condition to treat. There are also people whose heart rate is fast and slow, more than 100 beats/min when fast, and less than 60 beats/min when slow, which is called fast-slow syndrome, and it is more troublesome to treat. 2, the pulse beat is extremely irregular, fast and slow inaccurate, strength and weakness may be atrial fibrillation, which is also one of the more common arrhythmia, atrial fibrillation in the elderly cardiovascular disease patients are more common. Atrial fibrillation is characterized by “three inconsistencies”, that is, the heartbeat is inconsistent, inconsistent speed, inconsistent pulse and heartbeat is inconsistent, that is, the heartbeat sometimes can not reach the pulse, atrial fibrillation, the greatest harm is easy to induce cerebral infarction. The biggest danger of atrial fibrillation is that it is easy to induce brain infarction. 3. If you feel discontinuous pulse with your own hand, with long intervals, and you feel uncomfortable in your heart, and you feel that your heart beats strongly once and then there is a period of pause or your heart beats as if you are riding in an elevator and suddenly falls, this may be premature beat or atrioventricular block. If a premature heartbeat is more than 5 beats per minute, even healthy people without heart disease should pay close attention to it and take medication to treat it. Premature beats can be categorized into atrial, atrioventricular, and ventricular premature beats, with ventricular premature beats being the most common. Whenever there are premature beats, it is recommended to actively seek medical attention to clarify the type and number. Self-measuring your pulse can give you some simple insight into your arrhythmia, but if your symptoms are severe, you still need to seek medical attention as soon as possible. Depending on your condition, your doctor will prescribe an electrocardiogram (ECG) or an ambulatory electrocardiogram (ECG) to accurately diagnose the type of arrhythmia and treat it with medication or radiofrequency ablation as soon as possible.
