Figure 1 The Kaplan-Meier survival analysis shows that the risk of developing arrhythmic events was higher for inducible than for noninducible asymptomatic Wolff-Parkinson-White subjects (p < 0.0001). At 60 months of follow-up, 111 of 115 noninducible and 18 of 47 inducible patients did not experience spontaneous arrhythmias.
