of the patients with inducible ventricular tachycardia , presentation with tachycardia rather than fibrillation was associated with a longer ventricular activation time on the signal-averaged ecg ( 181 +/- 33 versus 158 +/- 21 ms , p less than 0.02 ) and a longer cycle length of inducible ventricular tachycardia ( 290 +/- 61 versus 259 +/- 44 ms , p = 0.05 ) .
