Kaplan–Meier event-free survival estimates in the patient population during follow-up (group A vs. group B). The Kaplan–Meier curve shows a difference between group A (RFCA treatment in primary hospitalisation) and group B (no-RFCA in primary hospitalisation) in terms of total mortality, electrical storm recurrence and ventricular tachycardia recurrence at 864 ± 629 days of follow-up. A statistically significant difference in terms of total mortality is observed (log-rank test, p = 0.04)
