Figure 1 Comparison of survival between patients with and without inducible ventricular fibrillation (VF). This Kaplan-Meier curve compares the overall survival for patients with (dotted line = [VF(+)]) and without (solid line = [VF(–)]) inducible VF. There was no significant difference in survival between the two groups. The numbers at the bottom represent the number of patients at risk.
