Digoxin is widely used in the treatment of various heart conditions, namely atrial fibrilation and atrial flutter, both abnormal heart rhythms It is sometimes prescribed for heart failure that cannot be controlled by other medication. Antiarrhythmic agents are a group of pharmaceuticals that are used to suppress cardiac arrhythmias, such as atrial fibrillation, atrial flutter, ventricular tachycardia and ventricular fibrillation.

According to medical professionals, while the practice of anti-arrhthmic drugs is still prescribed to patients to prolong life, the details of this remain unclear. It had, at one time, been believed that life was prolonged after a heart attack with the suppression of arrhythmia. This may happen due to the pro-arrhythmic effect these drugs could potentially create in the patient.

The use of digoxin in heart problems during sinus rhythm(normal heart beat)was once standard, but is now controversial. While it appears that the increased force of contraction should lead to improved pumping function of the heart, its effect on prognosis is questionable; additionally, other effective treatments are available, making the use of the medication during sinus rhythm an unnecessary risk. Nor is Digoxin the first choice for congestive heart failure, although it can still be useful in patients who remain symptomatic despite proper diuretic and ACE inhibitor(another pharmaceutical regimen) treatment. It has fallen out of favor because it was proven to be ineffective at decreasing the duration of heart disease, as well as in the reduction of numbers of deaths with regard to congestive heart failure. It has been shown to increase quality of life in some cases.

Digoxin is usually given by mouth, but can also be given by IV injection in urgent situations. The half life is about 36 hours; it is given once daily, usually in 125 μg or 250 μg dosing. In patients with decreased kidney function the half life is considerably longer, calling for a reduction in dosing or a switch to a different medication, such as digitoxin, a similar medication.

Less frequent adverse effects include: acute psychosis, delirium, amnesia, and the possibility of life-threatening heart complications, including additional arrythmia episodes and heart failure. As far as overdose situations are concerned, Digoxin has been shown to increase risk of deadly overdose.
