Atria are paced from the right or left atrium, ventricles are paced from the right ventricular apex or right ventricular outflow tract, and cardiac conduction is recorded. Various mapping techniques are available. Programmed stimulation techniques may be used to trigger and terminate a reentrant arrhythmia. Tilt table testing is used to evaluate syncope in Younger, apparently healthy patients and Elderly patients when cardiac and other tests have not provided a diagnosis. Tilt table testing produces maximal venous pooling, which can trigger vasovagal (neurocardiogenic) syncope and reproduce the symptoms and signs that accompany it (nausea, light-headedness, pallor, hypotension, bradycardia).
