A member asked:
Will acetylcholine raise cardiac output?
4 doctors weighed in across 2 answers
Not expected to: Acetylcholine (parasympathetic nervous system) should have the opposite effect from Epinephrine (sympathetic nervous system) and therefore should slow the heart rate and decrease the force of contraction of the heart. Both effects would tend to lower the cardiac output (stroke volume times the heart rate). The stroke volume is the amount of blood ejected with each heart beat.

No: Acetylcholine neurotransmission has an inhibitory effect on the heart, which lowers heart rate thereby decreasing cardiac output.
