Vagus Nerve

By releasing acetylcholine, how does the vagus nerve lower heart rate?
 
Acetylcholine is a neurotransmitter released at nerve synapses that lowers heart rate (bradycardia). Its just one of its chemical properties. Norepinephrine is another neurotransmitter, except this one increases heart rate (tachycardia).
 
Yes but what I want to know is the precise mechanism of action of acetylcholine to lower heart rate?
