- increases myocardial contractile force (hearts ability to squeeze- will increase

it), alters electrical activity of the heart (decreases rate of electrical conduction

and prolongs refractory period- decreases HR and slows the heart), affects

neuro-hormonal systems.

What do we treat with the use of digoxin?

- adjunct to heart failure, Afib

What are important side effects with digoxin use?
