Systems, apparatuses, and methods for electroporation ablation therapy are disclosed, with a protection device for protecting electronic circuitry, devices, and/or other components from induced currents and voltages generated during a cardiac ablation procedure. A system can include an ablation device near cardiac tissue of a heart. The system can further include a signal generator configured to generate a pulse waveform, where the signal generator coupled to the ablation device and configured to repeatedly deliver the pulse waveform to the ablation device in synchrony with a set of cardiac cycles of the heart. The system can further include a protection device configured to suppress induced current and voltage in an electronic device coupled to the protection device.
