The vagus never innervates the heart and affects the SA node. Otto Loewi discovered that the vagus nerve through the action of Ach (a neurotransmitter) slowed the heart. So the vagus nerve can slow the action (or beating) of the heart.
the heart rate would increase almost immediately by about 25 beats per min, reflecting the inherent rate (100 beats per min) of the pacemaking SA node
When the nerves to the heart are cut, the autonomic nervous system's regulation of heart rate is disrupted. The sympathetic nervous system, which generally increases heart rate, may become unopposed due to the loss of parasympathetic input from the vagus nerve, which normally slows the heart rate. This imbalance can lead to an increase in heart rate as the heart operates without the usual inhibitory signals. Additionally, the heart has intrinsic pacemaker cells that can generate impulses independently, contributing to an increased heart rate.
Who cut whose heart?

Yes, it is possible to cut nerves when piercing an eyebrow, particularly if the piercing is done improperly or too deep. The eyebrow area contains several nerves, and if a needle or jewelry comes into contact with them, it can lead to pain, numbness, or complications. To minimize risks, it's important to have piercings done by a professional who understands the anatomy of the area.
