title: Effects of chronic vasodilator therapy to enhance susceptibility to vasovagal syncope during upright tilt testing.
abstract: To evaluate the effect of chronic vasodilator therapy on susceptibility to vasovagal syncope, 45 patients with syncope and a positive response to tilt testing were randomly assigned to continue or to discontinue vasodilators. The study result demonstrated that chronic vasodilator therapy enhances susceptibility to vasovagal reaction during upright tilt testing.
