  • Publication number: 20190133483
    Abstract: A system for processing ECG recordings from multiple patients includes a preprocessing database containing unprocessed ECG records from multiple patients, a reporting database containing processed ECG records from multiple patients, a processor, and a triage module executable on the processor to assess each of the unprocessed ECG recordings from the multiple patients. The triage module is executable to detect a presence or absence of one or more known abnormalities and determines at least one abnormality identifier based on the detected known abnormality. One or more abnormality groups are then identified based on the abnormality identifiers. A normal group of ECG recordings from multiple patients is then identified from those ECG recordings that are not in the abnormality group. The normal group of ECG recordings is then stored in the reporting database then associated a normal identifier.

  • Patent number: 9603539
    Abstract: A system for modeling electrical activity of an anatomical structure. The system includes a database that is configured to store cell set data corresponding to a group of cells of the anatomical structure. The cell set data includes a cell model that represents electrical activity of the group of cells. The cell model has a model parameter that relates to ion channels in the cells. The electrical activity represented by the cell model is at least partially based upon the model parameter. The system also includes a user interface that is configured to accept user inputs to change the model parameter and thereby change the electrical activity represented by the cell model to form a reconfigured cell model. The system also includes a display that is configured to display the user inputs and a processor that is configured to determine the electrical activity of the anatomical structure using the reconfigured cell model.

  • Patent number: 8571644
    Abstract: A method and apparatus for analyzing characteristics of ECG signal data having a succession of waveforms produced by the beating of the heart. ECG signal data is obtained from a patient. A depolarization feature and a second feature of the waveforms of the ECG signal data are determined. Waveforms of the ECG signal data having a stable heart rate are selected for use in determining the second feature. Waveforms selected are those having minimum depolarization feature standard deviation and minimum depolarization feature dispersion. The depolarization feature and second feature for the heart beats of the selected waveforms are displayed.

  • Patent number: 8352018
    Abstract: In a multi-tier patient monitoring data analysis system, an algorithm server is positioned as a middle tier between an acquisition device, such as a cardiograph or patient monitor that can be seen as a lower tier, and a storage device for a database, such as that of a central computer for a hospital or clinic that can be seen as an upper tier. The algorithm server gathers current data from the real time acquisition device and obtains previously stored ECG signal data from the database. The algorithm server contains ECG analysis algorithm(s) and runs one or more algorithms using the current and previously acquired ECG signal data. Analysis algorithms may also be run on the acquisition device. The system provides the rapid, extensive, and thorough ECG analysis that is critical to patient welfare.

  • Patent number: 8260406
    Abstract: A system and a method for analysis of ECG curvature, which system involves a mathematical analysis comprising the following features where a number of different parameters are isolated and stored in a computer, where a first number of parameters are selected from at least one main group, where the selected parameters are combined in at least a first mathematical analysis. It is the object of the invention to improve mathematical analysis of ECG curvature particular for complex parts of the curvature such as notches or concavities. This can be achieved by selecting parameters from groups of symmetry, flatness, duration and/or complexity, using the parameters as input to an algorithm, where concavity intervals are evaluated on subsegments of the ECG segment and form the basis of up and downwards concavity quantification, where the system based on an algorithm detects and quantifies concavity on ECG curvatures.

  • Patent number: 8068900
    Abstract: Method and apparatus for determining alternans data of an ECG signal. The method can include determining at least one value representing at least one morphology feature of each beat of the ECG signal and generating a set of data points based on a total quantity of values and a total quantity of beats. The method can also include separating the data points into a first group of points and a second group of points and generating a feature map by plotting the first group of points and the second group of points in order to assess an alternans pattern of variation.

  • Publication number: 20110251507
    Abstract: A method and apparatus for analyzing the QT interval characteristics of ECG signal data having a succession of waveforms produced by the beating of the heart. ECG signal data is obtained from a patient. The R-R interval and the QT intervals of the waveforms of the ECG signal data are determined. Waveforms of the ECG signal data having a stable heart rate are selected for use in determining the QT interval characteristics. Preferably, the waveforms selected are those having minimum R-R interval standard deviation and minimum R-R interval dispersion. The QT correction (QTc) is computed from the ECG signal data waveforms selected in the foregoing manner or on the basis of clinician editing. The R-R intervals, the QT intervals, and QTc for the heart beats of the selected waveforms are displayed for analysis and diagnosis purposes. The invention can also be used, in an analogous manner, to obtain and display other cardiac data from the ECG waveforms.
