Classification: CPC A | IPC A

Claim 0:
1. A system, comprising:
a set of ablation electrodes disposable near cardiac tissue of a heart;
one or more sensors disposable near patient anatomy spaced from the set of electrodes, the set of sensors configured to be selectively coupled to and decoupled from an electronic device;
a signal generator configured to generate a pulse waveform, the signal generator coupled to the set of electrodes and configured to repeatedly deliver the pulse waveform to the set of electrodes;
a protection circuit configured to selectively couple and decouple the electronic device to and from the set of the sensors, the protection circuit including a plurality of sets of switches, including:
a first set of switches configured to switch between a conducting state in which the electronic device is coupled to the set of sensors, and a non-conducting state in which the electronic device is decoupled from the set of sensors; and
a second set of switches configured to selectively couple and decouple a set of channels associated with the set of sensors to and from a common node; and

a processor coupled to the protection circuit, the processor configured to:
control the first set of switches to cause the first set of switches to transition from the conducting state to the non-conducting state during a first time interval; and
control the second set of switches to couple the set of channels to the common node during a second time interval, wherein the second time interval begins before and ends after the first time interval.
