Abstract
Systems and methods for unipolar Pulse-Field Ablation (PFA) are disclosed for reducing spasm and/or other adverse nerves stimulation effects during delivery of PFA pulses. The system includes or is connected to one or more motion sensors to be placed at one or more regions of a patient's body for monitoring spasm thereat. The system includes a signal switch capable of selectively connecting a PFA energy generator to selected one or more of return electrode patches for delivery of PFA pulses and/or pacing signals through the selected electrode patches; and a processor that monitors motion sensed by the motion sensor(s) during delivery of the PFA pulses or pacing signals to identify nerve stimulation effects, such as spasm, to facilitate, based on the monitoring, selection of certain electrode patches by which the PFA pulses may be delivered without, or with reduced spasm or other adverse effects of excessive nerves stimulation.
