first one shoudl be ach, increasing the amount of impulses leads to increase Ca, lead to tetany

2nd one your are right , ca atpase , relaxation is an active process.

adenosine should decrease, adenosine is part of the normal autoregulation of blood flow in coronary vasculature, ischemia increases adenosine, I assume the reverse .
