VF vulnerability after IKAS blockade in the heart failure substrate. (A) ECG recording during VF at baseline (shock terminated) and after apamin infusion (self-terminated). Sustained VF was defined as lasting at least 180 seconds before a shock was delivered. Summary data in Panels B and C show that apamin increased the number of VF episodes that self-terminated which corresponded to a shorter VF duration.
