The electrocardiograph examination is mainly for patients with heart disease or suspected heart disease. If your body shows heart-related symptoms such as palpitations, palpitation, rapid heartbeat, etc., an ECG is required to determine the condition.
An ECG is a record of the electrical activity of the heart on the body surface. The clinical application of ECG has been for a long time and has a history of more than 100 years. Today's ECG machines are becoming more and more perfect. Not only the record is clear, the anti-interference ability is strong, but also the operation is simple and safe to use. It is currently the most commonly used early diagnosis method for coronary heart disease, myocardial ischemia, myocardial infarction and various arrhythmia.
ECG monitoring of coronary heart disease mainly includes three aspects: first, ST-segment changes, mainly including ischemic ST-segment depression, ST-segment extension, and ST-segment elevation or unidirectional curve; second, T-wave changes, mainly Described as low or inverted T wave. The doctor can make a diagnosis of the patient's condition by observing and analyzing the above two aspects.
Although ECG examination is regarded as an important clinical reference data for the diagnosis of coronary heart disease, it is not the only reference basis. In the non-onset period of coronary heart disease, the detection rate of the disease by ordinary ECG examination is only 30%-50%. Most of the patients' ECG is normal, and ordinary ECG can not be detected, which can easily delay the patient's condition.
Therefore, in clinical practice, we need to choose according to different needs. The two cannot be substituted for each other. Everything must follow the doctor’s advice and the doctor will determine the type of examination.
