  • Patent number: 11229392
    Abstract: Systems and methods for cardiac fast firing (e.g., atrial fast firing) detection perform frequency analysis on channels of collected cardiac waveform data and test the data for outlier frequency complex content that is of higher frequency than baseline frequency complex content associated with cardiac fibrillation (e.g., atrial fibrillation) or other arrhythmogenic activity. Anatomical regions from whence the cardiac fast firing originates can be displayed in real time on an epicardial surface map via a graphical display, aiding administration of therapy. Prior to such detection, QRST complex removal can be performed to ensure that ventricular activity does not infect the atrial fast firing analysis. A frequency-based method for QRST complex removal is also disclosed.

  • Patent number: 11123020
    Abstract: The invention provides a neck-worn sensor that is a single, body-worn system that measures the following parameters from an ambulatory patient: heart rate, pulse rate, pulse oximetry, respiratory rate, temperature, thoracic fluid levels, stroke volume, cardiac output, and a parameter sensitive to blood pressure called pulse transit time. From stroke volume, a first algorithm employing a linear model can estimate the patient's pulse pressure. And from pulse pressure and pulse transit time, a second algorithm, also employing a linear algorithm, can estimate systolic blood pressure and diastolic blood pressure. Thus, the sensor can measure all five vital signs along with hemodynamic parameters. It also includes a motion-detecting accelerometer, from which it can determine motion-related parameters such as posture, degree of motion, activity level, respiratory-induced heaving of the chest, and falls.

  • Patent number: 10244959
    Abstract: A vital information measurement device and a vehicle seat which improves the durability of sheet-shaped sensors configured to detect vital information of a seated passenger can stably measure the heart rate of the seated passenger. A vehicle seat includes sheet-shaped sensors attached to a seat back, and can measure the heart rate of a seated passenger based on vital signals of the seated passenger detected by the sheet-shaped sensors. At each sheet-shaped sensor, a sensor overlap reduction section is provided to reduce partial overlapping of the sheet-shaped sensor when the seated passenger leans on the seat back. Specifically, each sheet-shaped sensor includes a first cutout extending toward the center of the sheet-shaped sensor at an outer peripheral portion of the sheet-shaped sensor, and a second cutout formed continuously from the first cutout and extending opposite to the center along the outer peripheral portion of the sheet-shaped sensor.

  • Patent number: 10117589
    Abstract: A vehicle seat includes sheet-shaped sensors configured to detect electric signals associated with the biopotential of a seated passenger, the vehicle seat being configured to remove noise caused due to static electricity to stably measure a bioelectric signal (e.g., heart rate) of the passenger. A seat back includes the sheet-shaped sensors. A cushion pad placed on a seat back frame is covered with a trim cover. Vertically-extending conductive fabric in a belt shape is disposed on an outer surface of the trim cover. The portion where the conductive fabric is disposed has a three-layer structure of the conductive fabric, a skin, and a wadding. A free end of the conductive fabric drawn into the seat back is provided with a J-hook hooked onto a lower frame bridging portion, thus part of the conductive fabric and the lower frame bridging portion contact each other to be electrically conductive with each other.

  • Patent number: 10111598
    Abstract: Various embodiments are described herein for a system, method, and device for identifying focal source locations of electrophysiological activity in an organ. The system, method and device may also be used to guide catheter ablation of the organ. An electrogram signal can be obtained from a location in the organ, and it can be determined if the electrogram is periodic and, if so, the corresponding periodicity cycle length. A plurality of peaks associated with the cycle length can be identified. The location can be identified as a focal source location when the periodicity cycle length and the plurality of peaks have focal source characteristics. Methods are also described for identifying a direction of wave propagation and identifying multiple periodicities within an electrogram signal.

  • Patent number: 10004415
    Abstract: An extended wear electrocardiography patch is provided. A flexible backing is formed of an elongated strip of stretchable spunlace material. A layer of stretchable adhesive is applied on at least a portion of a contact surface of the flexible backing, which defines a pair of openings on both ends. A non-stretchable circuit is axially affixed to an outward-facing surface of the flexible backing and has a pair of circuit traces. The flexible backing acts as a buffer between the non-stretchable circuit and the stretchable adhesive and prevents disadhesion of the flexible backing during bending. A pair of electrocardiographic electrodes are electrically coupled to each of the circuit traces. Conductive gel is provided in each of the openings and in electrical contact with the pair of electrocardiographic electrodes as the electrodes shift away from the openings in the flexible backing during the bending.

  • Patent number: 9918678
    Abstract: A physiological monitoring system features a Floormat and Handheld Sensor connected by a cable. A user stands on the Floormat and grips the Handheld Sensor. These components measure time-dependent physiological waveforms from a user over a conduction pathway extending from the user's hand or wrist to their feet. The Handheld Sensor and Floormat use a combination of electrodes that inject current into the user's body and collect bioelectric signals that, with processing, yield ECG, impedance, and bioreactance waveforms. Simultaneously, the Handheld Sensor measures photoplethysmogram waveforms with red and infrared radiation and pressure waveforms from the user's fingers and wrist, while the Floormat measures signals from load cells to determine ‘force’ waveforms to determine the user's weight, and ballistocardiogram waveforms to determine parameters related to cardiac contractility.
