Elevated Hemi-diaphragms as a Cause of ST-segment Elevation: A case report and review of literature.

abstract：BACKGROUND:Atrial fibrillation occurs in 20% to 40% of patients post cardiac surgery. Prophylactic amiodarone decreases the incidence of atrial fibrillation, especially in those not taking β-blockers. Studies, however, vary in dosage, duration of treatment, and route of administration. Limited studies evaluating short ...
