Vasodepressor Syncope

Vasodepressor syncope is frequently observed, usually benign and self limiting process. Syncope in general terms refers to a sudden, transient loss of consciousness that is usually secondary to a period of cerebral ischemia.

Synonyms Of Syncope of Vasodepressor Syncope

  • Vasodepressor syncope

  • Atrial bradycardia

  • Benign faint

  • Neurogenic syncope

  • Psychogenic syncope

  • Simple faint

  • Vasovagal syncope

  • Swoon

Predisposing Factors of Vasodepressor Syncope

Psychogenic Factors

  • Fright

  • Anxiety

  • Emotional Stress

  • Receipt of unwelcome news

  • Pain, especially of a sudden and unexpected nature

Non-Psychogenic Factors

  • Exhaustion

  • Poor physical condition

  • Hot, humid and crowded environment

  • Age between 16 to 35 years

  • Hunger from dieting or a missed meal

  • Sitting in upright or standing position

Clinical Manifestation of Vasodepressor Syncope

Early signs and symptoms

  • Feeling of warmth

  • Loss of color, pale or ashen-gray skin tone

  • Heavy perspiration

  • Complains of feeling “bad” or “faint”

  • Nausea

  • Blood pressure approximately at baseline

  • Tachycardia

Late signs and symptoms

  • Pupillary dilation

  • Yawning

  • Hyperapnea

  • Coldness in hands and feet

  • Hypotension

  • Bradycardia

  • Visual disturbances

  • Dizziness

  • Loss of consciousness

Pathophysiology of Vasodepressor Syncope

  • Increase in anxiety causes increase in release of catecholamines

  • Increase in catecholamines causes decrease in peripheral vascular resistance which leads to pooling of blood in peripheral organs

  • Due to pooling of blood in peripherals cause decrease in atrial blood pressure which activates the compensatory mechanism

  • Increase in heart rate, breathing is rapid, pallor and perspiration leads to occurance of decompensation

  • This leads to the cause of hypotension and decrease in cerebral blood flow which ultimately leads to syncope

Management of Vasodepressor Syncope

  • Assess consciousness

  • Activate office emergency team

  • Position patient in supine position with feet elevated

  • Assess and open airway

  • Assess airway patency and breathing

  • Assess circulation

  • Activate EMS(emergency medical services) if recovery is not immediate

  • Administer oxygen

  • Monitor the vital signs

  • Provide definitive management of unconsciouness using aromatic ammonia

  • Administer atropine if bradycardia persists

  • Maintain composure

  • Arrange escort home after complete recovery

  • If recovery is delayed activate EMS(emergency medical services)
