Vascular vagal syncope is a syndrome in which various stimuli mediate reflexes through the vagus nerve, resulting in dilation of small visceral and muscular vessels and bradycardia, sudden dilation of peripheral vessels, and reduced venous blood return to the heart, causing the heart to have a reflex action of accelerating and strengthening contraction, which in some cases can cause sudden slowing of the heartbeat and dilation of peripheral vessels due to excessive excitation of the vagus and parasympathetic nerves, resulting in lower blood pressure and cerebral hypoxia, manifested as arterial hypotension with transient loss of consciousness, which can recover on its own without neurological localization signs.
