Detailed explanation-1: -What is the Vagus Nerve? The vagus nerve, also known as the vagal nerves, are the main nerves of your parasympathetic nervous system. This system controls specific body functions such as your digestion, heart rate and immune system. These functions are involuntary, meaning you can’t consciously control them.

Detailed explanation-2: -The parasympathetic system exerts its effects primarily via the vagus (innervates the esophagus, stomach, pancreas, upper large intestine) and pelvic nerves (innervates the lower large intestine, rectum, and anus.)

Detailed explanation-3: -Heart rate issues Vagal nerve dysfunction can cause both slow and fast heart rates depending on the type of dysfunction. For example, overactivity can lead to bradycardia (or slow heart rate) while disease causing insufficient activity of the vagus nerve can lead to tachycardia (fast heart rate).
