12. A method of controlling a pulsed field ablation system, the pulsed field ablation system comprising a signal generator configured to generate a pulse waveform, a set of electrodes configured to receive the pulse waveform and generate a pulsed electric field in response to the received pulse waveform, a set of sensors disposed near the set of electrodes and capable of being selectively coupled and decoupled to and from an electronic device, a processor, and a protection circuit, the method comprising:
prior to delivering the pulse waveform to the set of electrodes:
coupling, via the protection circuit, a set of channels associated with the set of sensors to a common node;
decoupling, via the protection circuit, the set of sensors from the electronic device after coupling the set of channels to the common node;
delivering the pulse waveform to the set of electrodes while the set of electrode is disposed near cardiac tissue;
after delivering of the pulse waveform to the set of electrodes:
coupling, via the protection circuit, the set of sensors to the electronic device; and
decoupling, via the protection circuit, the set of channels from the common node.
