The cardiac examination includes physical examination and ancillary tests. The examination includes visualization, palpation, percussion and auscultation of the heart. Common auxiliary examinations include the following 1.Echocardiography Echocardiography can visually observe the structure and beating of the heart and blood vessels, and can understand the thickness of the atria and the movement of the heart valves, which can provide reliable data for cardiomyopathy and a series of heart diseases. 2.Coronary angiography and CT Coronary angiography is an X-ray guided arterial visualization to understand the condition of the arteries, blood flow rate and other issues. Coronary CT is a popular technique in recent years, mainly used to diagnose coronary artery disease and can check whether there are problems such as artery stenosis. 3.Electrocardiogram and 24-hour dynamic electrocardiogram Traditional heart examination items, simple and intuitive view of the heart’s beating and blood flow, can make accurate diagnosis of myocardial ischemia and arrhythmia. 24-hour dynamic electrocardiogram requires patients to wear professional equipment, 24 hours of testing, the patient’s daily life should be the same as before wearing, get up, eat, walk, rest, every moment of the electrocardiogram signal changes will be recorded. The changes in the ECG signal will be recorded. 4.Myocardial perfusion isotope imaging Myocardial perfusion isotope imaging is a technique to observe the distribution of blood flow in the myocardium, which can reveal the structure of the heart and its function, it is non-invasive, easy to repeat, and the results are accurate and reliable. Because it can reflect the function and metabolism of organs, it has become increasingly popular in the diagnosis, treatment and prognosis of cardiovascular diseases, and is now widely used in clinical practice. 5.Cardiac catheterization This requires a small incision at the wrist or thigh, and a professional catheter is inserted into the patient’s body, with blood transported to the heart, to understand the oxygen content and pressure changes in different parts of the heart cavity and large blood vessels, and more precisely whether there are abnormal shunts and specific parts of the shunts. The above is the content related to heart examination, hope it can help you.
