Think of digoxin as the force that is used to squeeze Positive inotropic medications, as their name implies, are a diverse group of medications that increase the strength of heart muscle contraction
Increased serum digoxin concentrations by >50%; digoxin toxicity may occur Amiodarone is a cardiac glycoside antiarrhythmic and inotrope which defies Vaughan Williams classification

Digoxin is used for the treatment of congestive heart failure (CHF) because of its inotropic effects on the myocardium and for the treatment of atrial fibrillation because of its chronotropic effects on the electrophysiological system of the heart

Acute heart failure (AHF) is defined as the sudden presentation or sudden aggravation of signs and symptoms of heart failure, often requiring hospitalisation
Digoxin is also used in patients with chronic heart failure secondary to left ventricular systolic impairment, in sinus rhythm, who remain symptomatic despite optimal doses of diuretics and angiotensin converting enzyme inhibitors, where it acts as an inotrope
Inotropes have been fundamental to resuscitation of acute cardiogenic shock for decades
It's not a particularly powerful inotrope, but it might be the safest (with close monitoring of digoxin levels)
A post-hoc analysis of the DIG trial At therapeutic doses digoxin is a positive inotrope, shortens AP duration, and at low doses has predominately parasympathomimetic effects; Multiple direct and indirect cardiovascular effects with both therapeutic and toxic consequences (see below) In addition, it has undesirable effects on CNS and gut; Cardiac effects Name: DIGOXIN (Lanoxin R): Classification: cardiac glycoside
