Amiodarone-associated optic neuropathy in the treatment of cardiovascular diseases
An increase in the growth of cardiovascular diseases has been observed in the last few years. Cardiac rhythm disturbances, especially atrial fibrillation, in absence of cardioversion and proper prophylaxis lead to thromboembolic complications. Drug therapy in rhythm disorders consists of the many an...
