Atrial septal defect-atrioventricular conduction defects syndrome is a complex condition that requires a combination of treatments. Treatment options may include medications to control the heart rate, surgery to repair the defect, and lifestyle changes to reduce the risk of complications. Medications used to treat this condition may include beta-blockers, calcium channel blockers, and antiarrhythmic drugs. Surgery may be recommended to repair the defect and restore normal blood flow. Lifestyle changes such as avoiding alcohol and caffeine, eating a healthy diet, and exercising regularly can also help reduce the risk of complications.
