You are testing a compound as cardioactive drug. You know the compound is an agonist of acetylcholine (ACh) at the relevant ACh receptor (AChR) on sinoatrial (SA) node cells. Briefly describe how the action of the drug likely would affect the electrical signal produced by the SA node cells. In respect of cardiac output, what would you expect to be the effect of this drug?
