Answer:
Latent.
Step-by-step explanation:
The calcium is the important component of the body as bone is made of calcium. The calcium ions are important for the generation of the action potential and plays an important role in the muscle contraction.
The calcium channel blocker can decrease the amount of the intracellular calcium. This affects the latent stage of myogram as this steps involve the release of the calcium ions and no calacium ions are present due to the use of Diltiazem.
Thus, the answer is latent.
