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). cilrhedyn weather
