The biochemical mechanism of action of digitalis is associated with:
Digoxin is a cardiac glycoside. It directly inhibits Na-K ATPase and increases intracellular Na and decrease the extrusion of calcium. Thus increases intracellular Calcium. By increasing the calcium content and sodium content, force of contraction increases. (Ref-Essential of medical pharmacology K D TRIPATHI 6 Edition)
An increase in conduction from atrium to ventricle
An increase in ATP synthesis
An increase in systolic intracellular calcium levels
A block of calcium channels
