How Digoxin Works in Heart Failure
How Digoxin Works in Heart Failure
Mechanism of Action
Mechanism of Action
Digoxin works by influencing the balance of calcium in cells. It increases calcium levels in the heart, which strengthens heart muscle contractions and improves the heart’s pumping efficiency. This is crucial for heart failure patients who typically have weakened heart muscle function.
Effects on Heart Rhythm
Effects on Heart Rhythm
Beyond strengthening the heart muscle, digoxin helps regulate heart rhythm, especially in cases of atrial fibrillation. It slows down the conduction of electrical impulses through the atrioventricular (AV) node, thus helping to control heart rate. Read more on effective treatments at Used For.
