Isoproterenol during tilt testing may provoke life-threatening polymorphic VT; this case leaves open its safety implications for syncope protocols.
Case Report (n=1)
Isoproterenol infusion during tilt table testing can induce life-threatening polymorphic ventricular tachycardia even in the absence of ischemia, QTc prolongation, or electrolyte abnormalities.
Gatzoulis et al. (1995) conducted a case report in Syncope and probable dysfunction of the sinus node (n=1). Tilt table testing with intravenous isoproterenol was evaluated on Polymorphic ventricular tachycardia. Tilt table testing with intravenous isoproterenol induced life-threatening polymorphic ventricular tachycardia in a 44-year-old man with syncope and probable sick sinus syndrome.
