Sinus rhythm P wave widening, high lateral wall appear suspicious abnormal Q wave consider mitral valve disease, myocardial infarction, etc., can follow the doctor’s instructions to give rivaroxaban and other drug treatment, if necessary, surgical treatment. The widening of P wave in sinus rhythm is considered to be the enlargement of the left atrium, which is common in mitral stenosis. In the period of remission, we should focus on controlling the progression of the disease, and control the heart failure after it occurs, and control the ventricular rate of patients with atrial fibrillation and give them anticoagulant therapy, such as rivaroxaban, and in serious cases, we need to carry out mitral valve replacement surgery. Suspected abnormal Q waves in the high lateral wall should be considered as possible myocardial infarction, and antiplatelet, lipid-lowering and plaque-stabilizing drugs, such as clopidogrel and atorvastatin calcium tablets, should be given. Coronary arteriography should be carried out if necessary, and stent implantation should be given to some patients or coronary artery bypass grafting treatment should be given. The specific treatment should be determined by the cardiologist according to the patient’s condition.
