Each beat of your heart begins with an electrical signal from within your heart muscle. Two nerve systems- the parasmpathetic and the sympathetic nerves regulate your heart rate with TWO sets of chemicals called - adrenergic (epinephrine/norepinephrine) and cholinergic (acetylcholine)

These bind to receptors and raise/lower heart rate, blood pressure, artery contraction forces etc.

Adrenergic neurotransmitters are sympathetic and increase b.p., heart rate, dilate coronary arteries Cholinergic neurotransmitters are parasympthetic and decrease b.p., heart rate, constrict coronary arteries. Vagus nerve is one such nerve and is very important
