Dromotropic
Dromotropic
Dromotropic (pronunciation: droh-MOH-trop-ik) is a term used in medicine to describe the effect on the speed of conduction in the AV node in the heart. The term is derived from the Greek words "dromos" meaning race or course, and "tropos" meaning a turning.
Etymology
The term "dromotropic" is derived from the Greek words "dromos" (δρόμος), meaning 'race' or 'course', and "tropos" (τρόπος), meaning 'a turning'. In a medical context, it refers to the effect on the speed of conduction in the AV node in the heart.
Definition
In cardiology, a dromotropic agent or effect is one which affects the conduction speed (in either a positive or negative way) in the AV node, and subsequently the rate of electrical impulses in the heart. Positive dromotropy increases conduction velocity (for example, by increasing the influx of calcium ions), while negative dromotropy decreases conduction velocity.
