  • Publication number: 20190365250
    Abstract: Systems, methods, and computer program product embodiments are disclosed for displaying cardiac signals based on a signal pattern. An embodiment operates by accessing an input cardiac signal. The embodiment matches a portion of the input cardiac signal to a known signal pattern. The embodiment then displays an indication of a degree of the match.

  • Publication number: 20190343414
    Abstract: Systems, apparatus, and methods are disclosed for conveying signals between a patient and monitoring and treatment devices. An EP system provides large-signal input protection and RF ablation signal noise suppression while preserving the integrity of relevant components of small signals. The EP system has a low-noise amplifier topology with minimal hardware filtering. An input protection circuit shunts to ground signals with amplitude above an ablation voltage. An RF filter circuit linearly attenuates the signals between 300 kHz and 600 kHz. A low-frequency feedback circuit drives a common mode node of the RF filter circuit for additional attenuation. A signal amplification circuit amplifies the signals between 0.01 Hz and 1000 Hz. A fast recovery circuit feeds back a low-frequency voltage signal to the signal amplification circuit to gradually reduce offset voltage of the signals. A high-resolution A/D converter converts the signals from the signal amplification circuit to clean digital signals.

  • Publication number: 20190349310
    Abstract: Systems, methods, and computer program product embodiments are disclosed for processing and displaying multiple signals in near real-time. An embodiment operates by processing, using a first digital signal processor (DSP) of a first signal module, a first packet associated with a first signal. The embodiment also processes, using a second DSP of a second signal module, a second packet associated with a second signal. The embodiment equalizes a first processing delay associated with the first DSP with a second processing delay associated with the second DSP such that the first DSP completes processing of the first packet approximately simultaneously with the second DSP completing processing of the second packet. The embodiment then displays the processed first packet approximately simultaneously with the display of the processed second packet.

  • Publication number: 20190348975
    Abstract: Apparatus and methods remove a voltage offset from an electrical signal, specifically a biomedical signal. A signal is received at a first operational amplifier and is amplified by a gain. An amplitude of the signal is monitored, by a first pair of diode stages coupled to an output of the first operational amplifier, for the voltage offset. The amplitude of the signal is then attenuated by the first pair of diode stages and a plurality of timing banks. The attenuating includes limiting charging, by the first pair of diode stages, of the plurality of timing banks and setting a time constant based on the charging. The attenuating removes the voltage offset persisting at a threshold for a duration of at least the time constant. Saturation of the signal is limited to a saturation recovery time while the saturated signal is gradually pulled into monitoring range over the saturation recovery time.
