Correct answer: D. Ionotropic effect
- A. Chronotropic effect
- B. Dromotropic effect
- C. Bathmotropic
- D. Ionotropic effect
Explanation
The force of cardiac contraction is described by the inotropic effect, so the intended answer is option d, although it is misspelled as “ionotropic.” Chronotropic refers to heart rate, while dromotropic refers to conduction velocity.
