Electrocardiogram shows myocardial ischemia need to clarify the cause of the disease, such as physiological can be without special treatment, such as coronary heart disease, cardiomyopathy, etc., in accordance with the doctor’s instructions to be taken to improve the metoprolol, nitroglycerin and other drugs. 1. Physiological myocardial ischemia: After strenuous exercise, ECG test may indicate myocardial ischemia, and no drug intervention is needed. 2. Coronary heart disease: Myocardial ischemia can be caused by coronary artery stenosis or partial occlusion, at this time, it is necessary to adjust the lifestyle, such as light diet, reduce mental stress, pay attention to rest, do not stay up all night, and so on. At the same time to be metoprolol, isosorbide nitrate, nifedipine and other drugs to reduce myocardial oxygen consumption, improve ischemia, relieve symptoms, if necessary, coronary intervention. 3. Cardiomyopathy: dilated cardiomyopathy, hypertrophic cardiomyopathy and restrictive cardiomyopathy can cause myocardial ischemia on ECG, at this time, we need to slow down the progress of the disease, and give symptomatic treatment, such as hydrochlorothiazide, metoprolol, digitalis and other anti-failure treatments, and amiodarone anti-fibrillation treatment. If the ECG shows myocardial ischemia, please consult a doctor in time, and the above drugs must be prescribed by a doctor.
