Systems and methods for signal acquisition and visualization

Abstract:

Systems, apparatus, and methods are disclosed for bi-directionally conveying biomedical signals between a patient and signal acquisition and processing devices. An electrophysiology (EP) system includes an analog input protection and filtering stage with a differential circuit to process the biomedical signals to and from the patient; a signal amplification stage with a differential amplifier circuit to amplify an output of the differential circuit; an analog-to-digital converter stage to digitize an output of the differential amplifier circuit; a communication module to interface between the analog-to-digital converter stage and a digital processing stage having a plurality of signal modules; at least one processor to execute the plurality of signal modules, applying frequency-selective filtering and signal processing algorithms to the output from the analog-to-digital converter stage, to extract high-frequency and low-amplitude features of the biomedical signals in frequency ranges of interest; and a display for pattern- and time-aligned visualization of the biomedical signals.
