Figure legends
Figure 1
J point elevation in the right precordial lead was defined as upward/downward notching or downward slurring with an amplitude ≥ 0.1 mV at the end of QRS to early ST segment in any of the right precordial leads (V1 and V2) in the 4th or 3rd ICS. Arrows indicate J point elevation in the 3rd intercostal space in patients with IVF.
Figure 2
Kaplan-Meier analysis of freedom from recurrent VF during follow-up. The IVF group with J point elevation in the 3rd ICS and the BrS group both had significantly higher recurrences of VF compared with the IVF group without J point elevation in the 3rd ICS.
