To determine whether there is any problem with the heart, physical examination, blood test, electrocardiogram, coronary artery enhancement CT to determine. 1. Physical examination: When there are obvious symptoms such as weakness, dizziness, headache, panic, chest tightness, chest pain, shortness of breath, difficulty in breathing, etc., it is necessary to go to the hospital for a physical examination in time to understand one’s physical condition and to make a preliminary judgment on whether or not there is a heart disease. 2. Blood test: Going to the hospital to take blood tests can determine whether there are problems with the heart, such as myocardial markers can determine whether there is myocardial damage, brain natriuretic peptide to determine whether there is cardiac insufficiency, and so on. 3. Electrocardiogram (ECG): Through ECG and dynamic electrocardiogram (EKG), ECG can determine whether there is any problem of arrhythmia such as ischemia, premature beats, conduction block and so on. Dynamic electrocardiogram records 24-hour electrocardiogram images, which is more favorable for judging arrhythmia, myocardial ischemia and other conditions. 4. Coronary Artery Enhancement CT: Coronary Artery Enhancement CT can determine whether there is coronary artery stenosis and understand whether the patient has coronary artery disease. Patients who are suspected of having heart disease are recommended to go to regular hospitals for examination and treatment according to medical advice.
