Digitoxin Can Act as a Short Term Cardiac Stimulant by Inhibiting

Question

Digitoxin can act as a short term cardiac stimulant by inhibiting the Na+-K+ pump.

Accepted Answer

Digitoxin inhibits the Na+-K+ pump, which increases intracellular Na+ and Ca2+ levels. This increased calcium can lead to increased cardiac contractility, making digitoxin a short term cardiac stimulant.
