What kind of medicine to take for st-t wave change can’t be generalized. st-t wave decline can take nitroglycerin, beta blocker; st-t wave transient elevation can take calcium antagonist; st-t wave elevation can take beta blocker. 1. st-segment drop is commonly seen in angina pectoris, which is the manifestation of myocardial ischemia, you can take nitroglycerin and β-blockers such as metoprolol and pranolol under tongue, which can improve the symptoms of myocardial ischemia. 2. A transient elevation of the st segment is common in variant angina pectoris, and calcium antagonists such as verapamil and diltiazem can be taken to slow down the heart rate and dilate blood vessels to improve the symptoms of myocardial ischemia. 3. st-segment elevation is common in myocardial infarction, you can take beta-blockers such as metoprolol and pranolol, etc., which can lower the heart rate by inhibiting the sympathetic nerve, reduce myocardial oxygen consumption and improve the prognosis. If the ECG examination appears abnormal, it is recommended to go to the hospital in time to find the cause of the disease and standardize the treatment.
