is a cardiac glycoside used to treat heart failure and some irregular heart rhythms. It is often used in conjunction with other drugs- typically diuretics and ACE inhibitors. Digoxin works by slowing down heart rate and increasing heart muscle contraction.

Be sure your veterinarian has an extensive history of your petís heart problems.
