A drug causes a (+) inotropic effect,a (-) dromotropic effect,and a (-) chronotropic effect.What drug response would you expect to observe?
A)Tachycardia
B)Low blood pressure
C)Ankle edema
D)Slow heart rate

Question

Quizplus · Accepted Answer

The (+) inotropic effect means that the drug increases the force of contraction of the heart. The (-) dromotropic effect means that the drug decreases the conduction velocity of electrical impulses through the heart. The (-) chronotropic effect means that the drug decreases the heart rate. Therefore, the overall effect of this drug would be a slower heart rate with stronger contractions, leading to a decreased cardiac output and possibly a decrease in blood pressure. Tachycardia (A) and ankle edema (C) would not be expected with this drug response.
