Applied tension treatment of vasovagal syncope during pregnancy.

Vasovagal syncope is a common clinical problem that is often difficult and expensive to diagnose and treat. Applied tension is a behavioral treatment approach that has been demonstrated to be efficacious for the treatment of vasovagal syncope associated with injection phobia. The present case study evaluated the treatment of vasovagal syncope in a 41-year-old pregnant patient with injection phobia. The treatment included the use of applied muscle tension to increase blood pressure and prevent syncope during graduated exposure to increasingly greater anxiety-provoking stimuli. After completion of the treatment, the patient was able to undergo a blood draw and other medical procedures involving exposure to needles, with significantly reduced anxiety and no episodes of syncope. Applied tension is an effective and relatively inexpensive treatment for patients with vasovagal syncope related to injection phobia and may hold promise as a treatment for other types of syncope.
