Abstract: A signal processing evaluator and methods that compare a digital waveform of a cardiac signal to a first processed signal generated by a test system such as an EP recorder or an EP mapping system and generates a first finding evaluating how well the test system filters non-cardiac signals or simulated body impedance. A simulator and methods that send cardiac signals including non-cardiac signals or simulated body impedance to a test system and to a signal processing evaluator for evaluation of the test system.

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.
