In these patients, regardless of Although digoxin does increase ventricular contractility, it is not associated with a significant alteration in the cardiac output in normal subjects
Positive inotropic agents used to treat heart failure with reduced ejection fraction (HFrEF) include intravenous phosphodiesterase (PDE)-3 inhibitors (eg, milrinone), beta adrenergic receptor agonists (eg, dobutamine), intravenous calcium-sensitizing agents (eg, levosimendan, available in some countries outside the United States), and digoxin (available in oral and intravenous Aug 15, 2023 · Common digoxin side effects may include: nausea, diarrhea; feeling weak or dizzy; headache, weakness, anxiety, depression; or
Digoxin induces an increase in intracellular sodium that will drive an influx of calcium in the heart and cause an increase in contractility
It works by increasing myocardial contractility, increasing stroke volume and blood pressure
It strengthens the force of the heart muscle's contractions, helps restore a normal, steady heart rhythm, and improves blood circulation

Digoxin is used for rate control in atrial fibrillation (AF), but evidence for its efficacy and safety after myocardial infarction (MI) is scarce and mixed
Rate control is a major part of therapy for all patients with AF
In patients with left ventricular systolic dysfunction in sinus rhythm, digoxin therapy has been associated with an Digoxin is used for treating adults with mild to moderate congestive heart failure and for treating an atrial fibrillation, an abnormal heart rhythm

Digoxin can be used in DCM patients, and it increases the intracellular calcium concentration transient [17][18][19], but also myocardial contractility, stroke volume, and blood pressure [9]
The recommendation is that these patients use a regimen of digoxin before starting dobutamine to decrease the risk of developing atrial fibrillation with a rapid ventricular response
Cardiac output increases Vasopressors and inotropes are medications used to create vasoconstriction or increase cardiac contractility, respectively, in patients with shock
In severe toxicity cases, administration of digoxin immune fab may be helpful to Digoxin was used by 18
A cardiac glycoside extracted from the foxglove plant, Digitalis lanata, it is used to control ventricular rate in atrial fibrillation and in the management of congestive heart failure with atrial fibrillation, but the margin between toxic and therapeutic doses is small
It’s not directly cause the decrease in HR nor contractility, but by blocking adrenergic effect, it then produce decrease HR and decrease contractility

The effect of digoxin on contractility and symptoms in infants with a large ventricular septal defect (VSD) is controversial
The most recognized mechanism of action of digoxin is its ability to augment myocardial contractility
For maximal early benefits in treating tachyarrhythmias, digoxin requires loading doses, which can be administered intravenously or orally
In heart failure patients, digoxin binds to and therefore reduces the Na ,K -pump content in skeletal muscle; this lower number of available functional Na ,K It is most commonly due to a chronic disease that results in a severe decrease in myocardial contractility, severe regurgitation or shunting, or severe diastolic dysfunction
