Survival analysis showing the comparison in the cumulative ventricular tachycardia (VT) recurrence-free survival between patients undergoing first and subsequent catheter ablation procedures. The table below the graph represents the number of events during each interval indicated on the X axis and the number of patients at risk at the beginning of that interval.
