Vagal hypertonia can be seen in healthy people and can resolve spontaneously, or it can be associated with disease and does not resolve spontaneously.
Vagal hypertonia can cause bradyarrhythmias characterized by slowed heart rate, which are more common in children. It can be seen in healthy children, especially during sleep, breath-holding and significant gastric dilatation, and in pediatric patients with pharyngeal sensitivity when the pharynx is examined with a tongue depressor. Vagal hypertonia can also present with increased bowel movements and diarrhea.
Vagal hypertonia occurs in healthy people and can be relieved by self-regulation or with growth and development; if it is caused by diseases, such as intracranial tumors and other lesions of the vagus nerve center, it usually cannot be cured by itself and needs to be treated for the cause.
After the phenomenon of high vagus nerve tone, you should consult a doctor in time to clarify the cause of the disease and then target treatment.
