ECG stands for electrocardiogram, which records the electrical activity of the human heart over a period of time. The human heart is made up of muscle tissue, which produces electrical signals that can be transmitted through the surface of the skin and recorded and analyzed by an ECG machine.The graph of an ECG reflects the electrical conduction in various parts of the heart and is an important basis for assessing how well the heart is functioning.
ECG can provide a lot of useful information, such as assessing heart rate, rhythm, and structure, among other things. It can reflect arrhythmias, myocardial ischemia, cardiac insufficiency, and structural abnormalities of the heart, among others. In addition, in clinical practice, ECG can be used for clinical diagnosis and prognostic assessment. By analyzing ECG data, it can help doctors detect diseases in time, formulate reasonable treatment plans, and predict patients' disease development and prognosis.
ECG has a wide range of applications in medicine, involving diagnosis, prevention, treatment, control and scientific research. In clinical work, ECG is one of the most commonly used tests, and it is well suited for the detection of many diseases, such as arrhythmia, coronary heart disease, myocardial infarction, and valvular disease, among others. In addition, with the development of medical technology, ECG has been able to be used in conjunction with other medical devices, such as cardiac ultrasound, CT, MRI, and blood tests, making diagnosis more accurate, rapid, and convenient.
