Both digitalis glycosides and beta-blockers slow atrioventricular conduction and decrease heart rate.
Amiodarone is an antiarrhythmic agent with negative chronotropic properties that may be additive to those seen with beta blockers.
In hypertensive patients who have congestive heart failure controlled by digitalis and diuretics, beta-blockers should be administered cautiously.
Both digitalis and beta-adrenergic receptor blocking agents slow AV conduction.
In some cases beta-blocker therapy can be continued while cardiac failure is treated with cardiac glycosides, diuretics, and other agents, as appropriate.
