Cardiac glycosides (digitalis preparations including digoxin and digitoxin) are used clinically in two situations: heart failure due to systolic dysfunction, and in certain supraventricular tachyarrhythmias [ 1 ]: Canadian Brand Name Digoxin is used to treat congestive heart failure, usually in combination with a diuretic (water pill) and an angiotensin-converting enzyme (ACE) inhibitor

Despite these therapies, he continues to complain of dyspnea with minimal exertion
Sinus arrest, varying degrees of AV with dissociation or escape rhythms may occur, including paroxysmal atrial tachycardia with AV block, junctional tachycardia, frequent ventricular ectopics and bigeminy Drug action For digoxin Digoxin is a cardiac glycoside that increases the force of myocardial contraction and reduces conductivity within the atrioventricular (AV) node
(2) The increase in intracellular sodium causes Serious side effects may be more likely in older adults and those who are ill or debilitated
