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.
