Describe the mechanism of how digitalis (AKA Oubain) works at a molecular level to increase contractility (positive ionotrope)? Discuss the ion gradients, how they were created/maintained for a cell at resting membrane potential and the effects of this drug that lead to its action (rise in what ion and where) on muscle contraction.
