FIG. 6. — Quantification of endocardial activation as a function of applied SS and tissue refractoriness (CI). (a) Percentage of the endocardial surface activated (V_m > −20 mV) by the shock 9 ms (left) and 20 ms (10 ms post-shock, right) after shock initiation as a function of CI for different applied SSs. (b) Percentage of the endocardial surface hyperpolarised (<−80 mV) by the shock 9 ms after shock initiation as a function of CI for different applied SSs. (c) Change in V_m over time following preconditioning stimulus, showing the refractory state of tissue when each shock is applied (CI, shown by red dotted-lines).
