Many pharmacological agents can be used to potentiate vagal tone on the heart therefore slowing the heart rate. Beta-blockers, muscarinic agonists and cardiac glycosides such as Digoxin are just a few that can be used. Vasovagal syncope can ensue during a period of emotional stress for example causing a sudden drop in blood pressure and heart rate....
Lesions to the CN X are rare. A lesion to the pharyngeal branches can lead to dysphagia (difficulty swallowing) due to the involvement with the muscles of the pharynx. As CN X innervates the Palatopharyngeus and Salpingopharyngeus muscles a lesion here will cause the Palatoglossal arch to drop leading to Uvula deviation away from the affected side....
As stated above a lesion to one of the RLN’s will cause dysphonia. A lesion to both RLN’s will cause aphonia (loss of voice) and a stridor (inspiratory wheeze). Paralysis of the RLN’s usually occur due to cancer of the larynx or thyroid gland or due to surgical complications.
