Abstract: A radio frequency (RF) ablation system and methods for using the radio frequency ablation system are disclosed. The RF ablation system may include an elongated member, an RF generator, and a processor. The elongated member may include a distal portion including one or more electrodes and the RF generator may be operatively coupled to one or more of the electrodes. The processor, which may be coupled to one or more of the electrodes, may obtain an output signal from the electrodes and may monitor changes in a frequency spectra of an electrical signal received with the output signal. The processor may determine a level of one or more characteristics that are proportional to an amplitude of the electrical signal, proportional to the frequency of the electrical signal, or proportional to both of the amplitude and the frequency of the electrical signal.
