摘要： A method can include storing input electrical signal data representing at least a given electrophysiological signal acquired from a patient. A non-local mean filter can be applied to the given electrophysiological signal, the non-local mean filter including a spatial filter component and an intensity filter component. The method can also include controlling parameters to establish weighting of each of the spatial filter component and the intensity filter component in response to a control input. Filtered signal data can be stored based on the applying and the controlling.

摘要： According to one embodiment, an ECG waveform detecting apparatus includes an input circuit and processing circuitry. The input circuit receives an ECG signal. The processing circuitry performs first detection of a specific waveform included in the ECG signal, performs update processing of a detection parameter for detecting the specific waveform based on a part of the specific waveform or result of the first detection, performs second detection of the specific waveform from the ECG signal by using the detection parameter after the update processing, and generates a synchronization signal based on information on the second detection.

摘要： A noise detection sensor structure provides hardware-assisted real-time artifact detection on a live bio signal of interest while that signal is being recorded. The structure is configured to detect and analyze the type of external noise, and to use information about the noise type (such as noise level, frequency range of noise, noise source) to improve signal quality and usability of the bio signal. Different algorithms can be used for each noise type detected. In some example cases, for instance, the structure is configured to at least one of extract noise from measurement signal, synchronize measurement with noise signal, change the software filter or analysis algorithm, change gain/filter settings of noise mitigation circuitry, and prompt user to assist as needed, based on the detected noise. Bad signal epochs can be discarded prior to recording, to efficiently use storage. Separate channel(s)/sensor(s) can be used, with different filtering/gain schemes, for noise detection.

摘要： A connector block that permits simultaneous and continuous interconnection of the three leads of the epicardial pacing wires, the pacemaker, and the ECG monitor on clear separately labeled connectors is provided. Circuitry is provided that allows the display of epicardial signals on the telemetry unit, while still preserving the ability to pace the heart from the pacemaker. When pacing the connector block prevents excessive loading of the pacer signals by the ECG monitor and/or damage to the monitor by the high-voltage pacer signals. The connector block may be used universally on all monitors without the need for sophisticated understanding of the electrical characteristics of the ECG monitor or concern for damage or improper signal loading.

摘要： An apparatus for producing information indicative of cardiac malfunctions, for example atrial fibrillation, includes a processing system for processing an analysis signal produced by a sensor system responsive to motion including cardiovascular motion. The processing system is configured to form a first indicator quantity indicating degree of concentration of the autocorrelation of the analysis signal to a point corresponding to zero time difference between analysis signal samples whose mutual correlation is expressed by the autocorrelation and a second indicator quantity indicating the spectral entropy of the analysis signal. The processing system is configured to determine an indicator of cardiac malfunction on the basis of at least the first indicator quantity and the second indicator quantity.

摘要： Provided is a method and apparatus for measuring a biosignal. The biosignal measurement method may include measuring, at a biosignal measurement apparatus, a biosignal using a biosignal measurement sensor; processing, at the biosignal measurement apparatus, the biosignal and converting the biosignal to a pulse signal using a first voltage distribution time constant circuit and a waveform converter; and counting, at the biosignal measurement apparatus, the pulse signal using a counter and generating first biometric information. The first voltage distribution time constant circuit may filter a signal of a specific frequency band from the biosignal based on voltage distribution using a series resistance included in the first voltage distribution time constant circuit.

摘要： A differential voltage measuring system is described. The differential voltage measuring system has a signal measuring circuit for measuring bioelectric signals, and an interference-signal measuring circuit coupled to the potential of the differential voltage measuring system and electrically connected to a fixed reference potential. In this case, the interference-signal measuring circuit is designed for measuring a current flowing from the potential of the differential voltage measuring system to the fixed reference potential. A differential voltage measuring system with an additional path is also described. Furthermore, a differential voltage measuring system with an averaging potential measuring method is described.

摘要： A body worn mobile medical monitoring device configured to minimize cable wiring from a sensor by placement of one or more sensor communication ports. The body worn mobile medical monitoring device includes a housing securable on a lower arm of a patient, a display, and a sensor communication port positioned on a side of the housing and configured to face a hand of the lower arm of the patient when the mobile medical monitoring device is mounted to the lower arm of the patient. The sensor communication port provides wired communication with a pulse oximetry sensor attached to a digit of the hand of the patient, and is positioned on the side of the housing such that a path from the port on the side of the housing to the digit of the patient is shorter than any other path from any other side of the housing to the digit.

摘要： Devices and methods are described that provide improved diagnosis from the processing of physiological data. The methods include use of transforms prior to submitting the data to a multiple level neural network. In one embodiment for ECG analysis, a template is used to subtract data that is not pertinent to the diagnosis and then a Fourier transform is applied to the time series data. Examples are shown with applications to electrocardiogram data, but the methods taught are applicable to many types of physiological data.
