Abstract
Aspects of the disclosure relate to an instrument for pacing, mapping, sensing, and/or ablating cardiac tissue that includes an electrogram filtering circuit. To supply radio frequency energy, the disclosed instruments are only optionally connected to a radio frequency generator. When connected to a generator, the electrogram filtering circuit can be provided in a handle of the instrument, or in a connector, for example, to protect the instrument from potentially high-powered radio frequency energy. Alternatively, various disclosed embodiments are capable of pacing/sensing as a standalone device. The connector can be provided separately from both the instrument and the generator. In some embodiments, the electrogram filtering circuit is adaptive to suit a variety of generators.
