What Is Dromotropic Effect?

A dromotropic agent is one which affects the conduction speed (in fact the magnitude of delay) in the AV node, and subsequently the rate of electrical impulses in the heart. Positive dromotropy increases conduction velocity (e.g. epinephrine stimulation), negative dromotropy decreases velocity (e.g. vagal stimulation).

What is a chronotropic effect?

Chronotropic effects (from chrono-, meaning time, and tropos, "a turn") are those that change the heart rate.
