Electrocardiogram records the heart activation process A weak electric current is transmitted to the body surface through human body tissues, and is recorded by an electrocardiogram recorder to form a dynamic curve, which is an electrocardiogram. A typical electrocardiogram mainly includes interwave period, comprehensive wave group, interwave period and
wave. See each entry. These bands were named after the first string-type electrocardiograph in 1998 and are still used today. Over the past century, the application and development of electrocardiogram has gone through several periods and has become one of the most commonly used and reliable methods for heart disease research, especially cardiac electrophysiology research. The method is simple and easy to implement, and has been gradually popularized in hospitals and clinics at all levels. The electrocardiogram can accurately reflect the normal or abnormal potential changes during atrium and ventricular activation. Mainly used for the diagnosis of atrial and ventricular hypertrophy, determination of the nature and location of myocardial infarction, diagnosis of pericardial myocardial inflammation and coronary insufficiency, diagnosis of various arrhythmias, and monitoring of the effects of drugs and electrolytes on the myocardium. , such as digitalis, quinidine, antimony, low calcium, low potassium and high potassium, can provide reference materials with diagnostic significance for some heart diseases. With the development of computer and electronic technology, as well as in-depth research on electrophysiology, the application of electrocardiogram has broader prospects. Depending on the location of the probing electrodes and the lead method, there are many recording methods for ECG. Conventional ECG micro

See each entry. An electrocardiogram can only record potential changes during myocardial activation. Therefore, its scope of application also has certain limitations. Generally speaking, conclusions about the heart's reserve function, valvular disease, and etiology diagnosis cannot be drawn solely from electrocardiogram changes.
Electrocardiography
Electrocardiography uses instruments to record the waveform of potential changes produced when the myocardium is excited from the surface of the human body, which is called an electrocardiogram. It represents
the comprehensive process of electrical activation of the entire heart. It is composed of waves and waves, reflecting the
bioelectrical changes during the generation, conduction and recovery of myocardial cell excitement. Electrocardiography is a science that uses an electrocardiograph to record the bioelectricity generated during heart activity from specific parts of the body
Since the invention of the electrocardiograph in 2001 and the pioneering of the study of electrocardiography, nearly a century of efforts by electrophysiologists have given us a clearer understanding of the basis of electrocardiography and formed a discipline. Theoretical and systematic electrocardiography has become increasingly widespread and mastered and applied by clinical workers. It plays its due role in clinical practice and has become an indispensable professional technology in medical science. Electrocardiography mainly studies the generation principle of electrocardiogram, analyzes the pattern of electrocardiogram to understand the heart activity, and assists in diagnosing the mechanism of heart disease and arrhythmia.
The performance of electrocardiogram and its clinical significance. Variation, electrocardiogram tracing analysis pattern changes. It has a unique role in diagnosing heart disease. In addition to the traditional electrocardiogram and vectorcardiogram, its research methods also include dynamic electrocardiogram, exercise stress electrocardiogram, sinoatrial node electrogram, high-frequency electrocardiogram, orthogonal electrocardiogram signal, and superimposed electrocardiogram ventricular late potential. They respectively represent different clinical meanings and values. In recent years, electrocardiography
has made great progress in theory and practice. Electrocardiography diagnosis has become an important topic in clinical medicine, especially in cardiac and internal medicine disciplines
