Inotropic vs. Dromotropic: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 27, 2023
Inotropic refers to the force of heart muscle contraction, while dromotropic relates to the speed of electrical conduction in the heart.

Key Differences

Inotropic effects influence the strength or force of heart muscle contractions. Dromotropic effects, in contrast, affect the rate of electrical conduction through the heart. Both terms are crucial in understanding cardiac function, but they target different aspects.

Inotropic agents can either strengthen (positive inotropes) or weaken (negative inotropes) heart contractions. Dromotropic substances, on the other hand, can either accelerate (positive dromotropes) or decelerate (negative dromotropes) the electrical signals in the heart.
