Inferior wall infarction refers to inferior wall myocardial infarction, which is more serious. Inferior wall myocardial infarction is a very serious cardiovascular disease and this type of myocardial infarction is prone to bradycardia and hypotension. While treating myocardial infarction, care must be taken to prevent bradycardia and hypotension, and rehydration therapy may be appropriate. If the patient develops a high degree of atrioventricular block, a temporary pacemaker can be installed, and atropine can be sedated or pushed if necessary. When lower wall myocardial infarction is detected, timely coronary intervention must be performed, which will largely help to save dying cardiomyocytes and improve the patient’s prognosis. Patients are advised to chew aspirin, clopidogrel, and atorvastatin before the procedure, which can have a reinforcing antiplatelet and lipid-lowering effect. Patients with lower wall infarction should go to the hospital in time for examination and treatment under the guidance of the doctor.
