Digoxin is widely prescribed for the treatment of congestive heart failure and various disturbances of cardiac rhythm. Used in the management of chronic cardiac failure where the dominant problem is systolic dysfunction.
Its therapeutic benefit is greatest in patients with ventricular dilatation.
Specifically indicated where cardiac failure is accompanied by atrial fibrillation
Used in the management of certain supraventricular arrhythmias, particularly chronic atrial flutter and fibrillation.
Therapeutic use of digoxin improves the strength of myocardial contraction and results in the beneficial effects of increased cardiac output, decreased heart size, decreased venous pressure, and decreased blood volume.
