A method for ablating tissue in a subject, including providing a probe, having an electrode, that is inserted into a lumen of the subject, so that the electrode is in proximity to the tissue to be ablated. An immobilizing signal is injected into the subject, via the electrode, that immobilizes the subject. When the subject is immobilized, an ablation signal is injected via the electrode into the subject, the ablation signal being configured to ablate the tissue of the subject by irreversible electroporation. The ablation signal has at least one train of first pulses, each of the first pulses in the at least one train having a first pulse absolute amplitude, and the immobilizing signal has one or more trains of second pulses, each of the second pulses in the one or more trains having a second pulse absolute amplitude less than the first pulse absolute amplitude.
