What tests can be done for heart discomfort?
1. Electrocardiogram
ECG is the most basic way of heart examination. It has important judgment significance for myocardial ischemia and arrhythmia, as well as heart size and heart rate beat. However, at present, ECG is divided into ordinary ECG and ambulatory ECG. Ordinary ECG refers to the problem detected in a certain period of time. Ambulatory ECG refers to monitoring the heart condition all day, which can make up for the deficiency that ordinary ECG can not show the problem without disease attack.
2. Cardiac color Doppler ultrasound
ECG can check whether the heart circuit is normal and judge the beating of the heart. Cardiac color Doppler ultrasound can understand the structure and function of the heart. It is of irreplaceable significance in the diagnosis of heart disease to evaluate the condition of heart valve by ultrasound, understand the size of cardiac cavity, and judge whether there is congenital heart disease, valvular heart disease, or other cardiomyopathy.
3. Cardiac radionuclide examination
Cardiac radionuclide phenomenon is also called cardiac isotope examination, which mainly uses radionuclide technology to examine the heart. The examination is simple, the dose received by the body is small and non-invasive. At present, it is widely used to judge coronary atherosclerosis or coronary heart disease.
4. Cardiac MRI has high resolution and contrast rate for soft tissue. It can evaluate the size of the heart, understand the inner diameter of the aortic root, pericardial structure and organs around the heart. Cardiac MRI also has important diagnostic significance in clinic, but this examination has high requirements for doctors, and only doctors with enough experience can accurately analyze it.
5. Coronary angiography
Patients with myocardial ischemia and angina pectoris can do coronary CT and inject contrast agent for comparison to understand the vascular situation. If there is no cardiovascular stenosis, coronary heart disease can be excluded.
6. Coronary CT
Multi slice spiral CT scan of coronary artery can not only detect vascular calcification, but also understand cardiac abnormalities. However, if it is arrhythmia or angina pectoris, the examination results will be misdiagnosed.
Medical information network believes that no matter what kind of heart examination project, there are precautions before and after the examination, such as relaxing the body and mind, wearing pure cotton clothes, removing metal objects worn by the body, etc. do a good job of precautions for examination according to the doctor's guidance, so as to make the results more accurate and prevent errors. In addition, pay attention to special groups, such as pregnant women, infants and lactating women, and inform the doctor of the situation before the examination to prevent injury caused by the examination.
