Abstract: A method of determining a pulsed field ablation waveform parameter for creating a desired lesion characteristic in cardiac tissue. The method of provides an electrosurgical generator configured to deliver electroporation pulses, the generator configured to: load predetermined waveform parameters (yi); load predetermined modeling data (xi); accept entry of a user inputted desired lesion characteristic (ui); and determine at least one corresponding pulsed field ablation waveform parameter based on (ui), (yi); and (xi).
