1. An electroporation ablation system, comprising:
a probe configured to be inserted into a body part of a living subject, and comprising a distal end including at least one electrode;
a plurality of body-surface patches configured to be applied to a skin surface of the living subject;
an ablation power generator configured to be selectively electrically connected to the at least one electrode and at least one of the plurality of body-surface patches, and configured to generate at least one first electrical pulse train, and apply the at least one first electrical pulse train between the at least one electrode and at least a first one of the plurality of body-surface patches; and
a processor configured to:
provide a measurement of movement of the living subject responsively to applying the at least one first electrical pulse train between the at least one electrode and the at least first one of the body-surface patches;
compare the measurement to a threshold; and
select at least a second one of the plurality of body-surface patches responsively to the measurement of movement of the living subject exceeding the threshold, and wherein the ablation power generator is configured to generate at least one second electrical pulse train, and apply the at least one second electrical pulse train between the at least one electrode and the at least second one of the plurality of body-surface patches.
