With the continuous development of medical technology, more and more people are undergoing cardiac surgery. However, the risks of heart surgery are relatively high. Before performing heart surgery, doctors need to evaluate the patient's heart condition to better determine surgical options and risks. Among them, electrocardiogram, as a simple, convenient, non-invasive examination method, is widely used in risk assessment before cardiac surgery.

An electrocardiogram is a test that records the heart's electrical activity to assess the function and condition of the heart.

It can display the rhythm and conduction of the heart and detect cardiac rhythm abnormalities, myocardial ischemia, myocardial infarction and other heart diseases. Before cardiac surgery, doctors can evaluate the patient's heart health through electrocardiogram examination, understand the patient's basic electrocardiogram changes, and determine whether the patient has intracardiac electrical problems and basic cardiac lesions before surgery.

Through electrocardiogram examination, doctors can determine whether the patient has serious cardiac electrical activity abnormalities, such as supraventricular tachycardia, ventricular tachycardia, etc., as well as sinoatrial conduction block, atrioventricular conduction block, etc. that affect cardiac diastole. Shrinkage problem. These problems can have a serious impact on the patient's surgical safety and must be promptly assessed and addressed before surgery.

In addition, ECG can also evaluate whether the patient has problems such as myocardial ischemia and myocardial infarction before surgery. Through electrocardiogram examination, doctors can observe changes in the ST segment to determine whether there is myocardial ischemia, and the appearance of Q waves to determine whether there is myocardial infarction. These problems need to be treated and dealt with promptly before surgery to ensure the safety of the surgery.

In short, as a simple, convenient, non-invasive examination method, electrocardiogram is widely used in risk assessment before cardiac surgery. Through electrocardiogram examination, doctors can evaluate the patient's heart condition, understand the patient's basic electrocardiogram changes, and determine whether the patient has intracardiac electrical problems and basic cardiac lesions before surgery. These evaluation results can help doctors formulate more scientific and effective surgical plans and provide patients with safer and more reliable treatments.
