Digitalis and Digoxin: Mechanism of Action and Role in Congestive Heart Failure

Explore the mechanism of action and role of Digitalis and Digoxin in Congestive Heart Failure through this comprehensive lecture. Delve into the pharmacology of these cardiac glycosides, focusing on their effects on the sodium-potassium ATPase in myocytes. Learn how inhibition of this enzyme leads to increased intracellular sodium and calcium levels, ultimately enhancing cardiac contractility. Understand the primary pharmacodynamic property of digitalis in increasing systolic contraction force and its secondary cardiovascular responses. Gain insights into the clinical applications of these medications in treating heart failure and their impact on cardiac function.
