Question
Modifiers that affect heart rate are _______.Question 20Select one:A.agonistsB.antagonistsC.inotropicD.chronotropic
Solution
The correct answer is D. chronotropic. Chronotropic effects are those that change the heart rate. Agonists and antagonists can be chronotropic if they affect the heart rate, but they can also affect other aspects of heart function. Inotropic effects are those that change the strength of the heart's contraction, not its rate.
