The standard electrocardiogram consists of 4 columns with 3 leads per column, namely I, II, III; aVR, aVL, aVF; V1, V2, V3; V4, V5, V6. The paper feed speed is usually 25 mm/s (12 s is recorded for 12 s). Sometimes a paper feed speed of 50 mm/s is also available, at which time only 6 leads are recorded per sheet.P wave and PR intervalSince the sinus node is located at the proximal end of the right atrium, and the depolarization is from right to left and top to bottom (from the proximal to the distal), the normal P waves are at I, II, aVF, and V4~ The V6 lead is positive. Atrial repolarization ...

ECG is the abbreviation of electrocardiogram, which means electrocardiogram, which means that the heart is excited by the pacemaker, the atria, and the ventricle in each cardiac cycle. With the changes of bioelectricity, various forms are drawn from the body surface through the electrocardiograph. A graph of potential changes.Ecg holter monitor is using to monitor the heart data.The significance of electrocardiogram examination is: for the examination of various arrhythmia, ventricular atrial hypertrophy, myocardial infarction, myocardial ischemia and other diseases.The electrocardiogram is an...

The results of electrocardiogram examination in patients with acute cerebrovascular disease generally include abnormal results such as arrhythmia, U wave, T wave, and ST-T segment changes. Patient laboratory tests for myocardial zymogram, troponin, myoglobin and other results have individual differences. Clinical experience is summarized as changes in ECG after onset of acute cerebrovascular disease. Some studies have shown that after the onset of acute cerebrovascular disease, the abnormal changes of ECG are related to the age of the patient. As the patient's age increases, the electrocardiog...

Atrial premature beats are clinically divided into sporadic and frequent atrial premature beats. Occasional atrial premature beats are often associated with hyperactivity, eating, fatigue, drinking, and long-term smoking. This premature beat often does not require special treatment; frequent premature beats are a pathological manifestation. The occurrence of such atrial premature beats is often associated with the application of drugs such as arteriosclerosis, rheumatic heart disease, coronary heart disease, viral myocarditis, and quinidine, digitalis, etc., at this time, the risk of atrial pr...

Perhaps we have had the experience that the car's engine will age when used for a long time. In fact, our heart is also true. The heart is in our body. It is an organ that can't stop for a moment. It pushes the blood circulation of the whole body and guarantees the metabolism of the human body. However, when the human body suffers from coronary heart disease, pulmonary heart disease, hypertensive heart disease, rheumatic heart disease and other diseases, it will not only increase the burden on the heart, but also cause myocardial damage. If these diseases are not controlled, the heart will be ...
