Cardiac glycosides The answer is D: cardiac glycosides 2. Digoxin helps the heart pump more efficiently by altering the inotropic, chronotropic, and dromotropic actions of the heart. Select all the options below that accurately describe these actions created by Digoxin: a. Positive Chronotropic b. Positive Inotropic c. Negative Inotropic d. Negative Dromotropic e. Negative Chrontropic f. Positive Dromotropic The answers are: B, D, and E. Digoxin creates a positive inotropic, negative chronotropic, and negative dromotropic action on the heart.
