Which of the following has a strong, positive inotropic effect, meaning it increases the strength of each contraction of the heart?

Missing choices:

A) Myocardial hypercapnia

B) Hypocalcemia

C) Hyperkalemia

D) Hypercalcemia

E) Myocardial hypoxia

I'm debating between two answer choices. A) Myocardial hypercapnia and E) Myocardial hypoxia.

Myocardial refers to the cardiac muscle or myocardium.

Hypercapnia is the excessiveness of carbon dioxide in the blood stream.

Hypoxia is the inadequate amount oxygen in the body.

I'll go with E) Myocardial hypoxia.
