Research indicates that children with more secure attachments with their mothers exhibited greater empathetic responsiveness, less social inhibition, and higher vagal tone, again highlighting the vagus nerve's regulatory effect on emotional and social function.

The most common causes of first-degree heart block are an AV nodal disease, enhanced vagal tone ( for example in athletes ), myocarditis, acute myocardial infarction ( especially acute inferior MI ), electrolyte disturbances and medication.

Since inhibitory effects of the VVC branch of the vagus allow for a wide range of adaptive, prosocial behaviors, it has been theorized that individuals with greater vagal tone are able to exhibit a greater range of such behaviors.

Typically, expression of RSA decreases with age; however, adults in excellent cardiovascular health, such as endurance runners, swimmers, and cyclists, are likely to have a more pronounced RSA . Professional athletes typically maintain very high vagal tone and RSA levels.

What doctors call vagal tone, the ability of the vagus nerve to automatically speed or slow the pulse on demand, has long been considered an indication of physical fitness; healthy adults drop their heart rates an average of 20 beats in the first minute after work stops, said Lauer, a cardiologist who is director of the clinic's exercise laboratory.
