Electrocardiography is a non-invasive detection method used to record the electrical activity of the human heart. By displaying images on paper or on a monitoring screen, it reflects the electrical signals transmitted during the beating and releasing of the heart.

With the continuous development of science and technology, electrocardiogram has a very wide range of applications in clinical medicine.

Electrocardiogram is one of the necessary tools for clinicians to diagnose cardiovascular diseases. For different types of heart diseases, the waveform characteristics displayed by the ECG are also different. For example, atrial fibrillation can be manifested as arrhythmia and irregular heartbeat, while ST segment changes can be manifested as acute myocardial infarction. The "12-lead ECG" examination method is very helpful in evaluating the overall function of the heart, diagnosing the location and scope of lesions, and can provide guidance for other auxiliary examination methods.

ECGalso plays a vital role in patient health management. At present, with the change of people's lifestyle, the prevalence rate of cardiovascular and cerebrovascular diseases is getting higher and higher, and the awareness of health care to prevent heart diseases is also gradually increasing. At this time, regular ECG examinations can detect potential heart problems early and improve the prediction accuracy of heart disease. In certain populations, such as hypertension, diabetes, etc., routine ECG examination is recommended.

In addition, with the rapid development of mobile medical technology, portable ECG monitoring equipment is becoming more and more popular. Users can operate and measure by themselves without the assistance of professional medical staff, independently judge and predict related diseases, and prevent them in time.

With the continuous advancement of medical technology, the role of electrocardiogram will be more prominent in patient health management in the future, escorting the health and safety of patients.
