Pilocarpine is a muscarinic receptor agonist and increases the activity of acetylcholine released by the parasympathetic nervous system thus slowing the heart rate (Silverthorn, 2009). Atropine on the other hand is a muscarinic receptor antagonist and competes with acetylcholine for binding on the receptors which means it blocks acetylcholine released by the parasympathic system and allows the heart rate to increase (Silverthorn, 2009).
