Needle phobia and malignant vasovagal syndrome [PDF]
Anaesthesia, 1998 A case is reported in which suspicion of malignant vasovagal syndrome was aroused by a history of faints and needle phobia. The vasovagal response was successfully avoided using a gaseous induction of anaesthesia with sevoflurane. Intravenous access was achieved under general anaesthesia.

Pediatric syncope in the emergency department: a risk-stratified diagnostic and disposition pathway [PDF]
International Journal of Emergency MedicineBackground Pediatric syncope accounts for 1–3% of emergency department (ED) visits. Although most cases are benign, 4% are caused by cardiac disease and 3% by seizures, which carry a risk of sudden death or neurologic injury if missed.

Sympathetic dysfunction in vasovagal syncope and the postural orthostatic tachycardia syndrome [PDF]
Frontiers in Physiology, 2014 Orthostatic intolerance is the inability to tolerate the upright posture and is relieved by recumbence. It most commonly affects young women and has a major impact on quality of life and psychosocial well being.

Vasovagal syncope and postural orthostatic tachycardia syndrome in adolescents: transcranial doppler versus autonomic function test results [PDF]
Clinical and Experimental PediatricsBackground Syncope is a temporary loss of consciousness due to cerebral hypoperfusion associated with autonomic dysfunction. Vasovagal syncope (VVS) and postural orthostatic tachycardia syndrome (POTS) are the most common causes of syncope in adolescents.
