It is my understanding the medication is used to increase contractility of the pumping chambers. My medication
for stablizing heart rate is a beta blocker (
coreg) and an ACE inhibitor.
My research: "Digoxin is contraindicated in patients with ventricular fibrillation. Digoxin should generally be avoided in patients with preserved left ventricular systolic function, although it has been used for ventricular rate control in the subgroup of patients with chronic atrial fibrillation.
