Nearly 2.6 million people die in my country every year in China, accounting for about 40%of the total deaths of all diseases. Nearly 40 % of patients with heart disease. This requires we need to pay attention to prevention. Any disease is found in the early days. The possibility of cure or improvement is high. Don’t wait until you feel that it is not suitable to do inspection. In fact, it is not difficult to prevent heart disease. As long as you do a healthy medical examination once a year, you can prevent it. Not only are heart disease, many physical diseases can be prevented and found early. So, what’s the use of health examination for ECG?
Maybe you do it every year, and you don’t understand what is going on. “It’s normal anyway, it’s OK.” Many people have such an idea. But once you have a problem, you will start to guess and find answers through various channels. Please don’t think of it to understand the electrocardiogram.
ECG is the process of biological electrical changes in the heart in each exercise cycle. It is a manifestation of the heart’s resurrection. It is the process of excitement in the pace point -atrium -ventricle.
Cardiac biological electrical activity is recorded on the ECG drawing through the body surface electrode. Commonly used leaders include 6 limb leadership (I, AVR, AVL, AVF) and 6 chest leaders, (V1, V2, V3, V4, V5, V6). Normal ECG graphics include P, QRS and T waves that appear in order, as well as periods between various waveforms, such as P-R interval periods, Q-T inter-periods. Analysis of the order of each waveform and changes in the baseline level can provide clues for the diagnosis of various heart diseases or systemic diseases.
This examination will be used to check various diseases such as arrhythmia, ventricular atrioventricular, myocardial infarction, arrhythmia, myocardial ischemia and other diseases. It can reflect the degree of myocardial damage and development process, and the functional structure of the atrium and ventricle. At the same time, it is important to note that the ECG test is not universal. Some myocardial damage and function defects are not always displayed. For preventive examinations in the heart, a variety of inspection items also need to be combined with a comprehensive analysis in order to make correct judgments.
What should I pay attention to when doing an electrocardiogram:

1) Before the inspection, you cannot drink, eat, eat cold drinks and smoke, and you need to rest for 20 minutes. If you have some heart problems, explain to the doctor so that she can conduct a corresponding examination, if you are taking drugs with abnormalities, you must also explain. Please do not test the doctor’s psychology for examination. The bad mentality may affect the results of the examination.
2) When checking, lie flat, relax the whole body, breathe smoothly, keep quiet, do not talk to the doctor, move your body.
