    • Vasovagal (situational) syncope, one of the most common types, may occur in scary, embarrassing or uneasy situations, or during blood drawing, coughing, urination or defecation.
    • In vasovagal syncope, the vagus nerve decreases blood flow to the brain.
    • Recurrent syncope with complex associated symptoms called neurally mediated syncope.
    • The vagus nerve, labeled at the top left and colored in yellow, may lower heart rate, reducing blood flow to the brain and causing vasovagal syncope.

  • Vagus (X) Nerve

    • Excessive activation of the vagal nerve during emotional stress can also cause vasovagal syncope due to a sudden drop in cardiac output, causing cerebral hypoperfusion.

    • This condition is called carotid sinus syncope, and results in dramatic changes in heart rate or blood pressure.
