The results of 206 programmed ventricular stimulation studies performed in 130 patients (100 men and 30 women, mean age 62 +/- 12 years, +/- standard deviation) were examined prospectively to determine the sequelae of nonsustained polymorphic ventricular tachycardia (VT) induced during programmed ventricular stimulation. The clinical indication for the electrophysiologic study was either docume...
