Abstract:
We studied 55 patients with syncope and structural heart disease using both tilt-table testing and electrophysiologic studies. Although sustained ventricular tachycardia was found in 21 of 55 patients (38%), and neuromediated syncope in 18 of 51 patients (35%), only 16% of patients with ventricular tachycardia had a positive tilt-table test.
