Voltages and currents induced by electroporation pulses on the disconnected ventricular lead for open contacts (a—voltage only) and shorted contacts (b, c) as a function of the distance between the electroporation and the pacemaker electrodes. For the amplitudes of electroporation pulses 1000 V (both conductivities) and 3000 V (lower conductivity only). Mean average values and ± SD bars are shown (N = 6–8). See Fig. 5 for the definition of distance D
