  • Patent number: 10258286
    Abstract: A stand-on physiological sensor (e.g. floormat) measures vital signs and various hemodynamic parameters, including blood pressure and ECG waveforms. The sensor is similar in configuration to a common bathroom scale and includes electrodes that take electrical measurements from a patient's feet to generate bioimpedance waveforms, which are analyzed digitally to extract various other parameters, as well as a cuff-type blood pressure system that takes physical blood pressure measurements at one of the patient's feet. Blood pressure can also be calculated/derived from the bioimpedance waveforms. Measured parameters are transmitted wirelessly to facilitate remote monitoring of the patient for heart failure, chronic heart failure, end-stage renal disease, cardiac arrhythmias, and other degenerative diseases.

    Abstract: An algorithm for determining heart rate by removing motion artifacts from a PPG signal in the frequency domain utilizes a principal component analysis. Some examples of the present disclosure process PPG signals in combination with accelerometer signals to remove unwanted artifacts in the frequency domain. For example, principal components of the accelerometer signal can be generated and combined with the PPG signal to filter out acceleration contributions represented in the PPG signal to reveal heart rate peaks. Additionally, in some examples, templates may be stored for correlation with candidate heart rate peaks to select those peaks with the highest correlations with the stored templates.

    Abstract: An apparatus and method for diagnosing and/or treating autonomic dysregulation is disclosed. In a preferred embodiment, a user is presented stressful audio-visual content at a known time. The resulting amount of deviation of the user's autonomic nervous system from stasis is automatically quantified periodically subsequent to the presentation of the stressful audio-visual content by monitoring a parameter of the user's heartbeat over time, thus automatically measuring both the amount of disturbance in the user's autonomic nervous system, and the re-settling time of the user's autonomic nervous system for given stressful audio-visual content. The apparatus may then guide the user through one or more awareness exercises, and subsequently re-measure the user's response to stressful audio-visual content.

  • Patent number: 9986918
    Abstract: Systems and methods to indicate heart failure co-morbidity are described. In an example, one or more physiological signals can be analyzed for a specified time period to determine at least one of an indication of a heart failure event or a characteristic of heart failure co-morbidity, such as a characteristic of a non-heart failure physiological event. At least one of the different physiological signals can be compared to a specified criterion indicative of the heart failure event to provide a comparison value, where the comparison value is indicative of whether the at least one of the different physiological signals contributed towards the indication of the heart failure event. An indication of a non-heart failure physiological event can be determined using the heart failure event indication, the non-heart failure physiological event characteristic, and the comparison value indicative of whether the one or more physiological signals contributed towards the heart failure event.

  • Patent number: 9974963
    Abstract: Embodiments of the invention provide methods for detection and treatment of atrial fibrillation (AF) and related conditions. One embodiment provides a method comprising measuring electrical activity of the heart using electrodes arranged on the heart surface to define an area for detecting aberrant electrical activity (AEA) and then using the measured electrical activity (MEA) to detect foci of AEA causing AF. A pacing signal may then be sent to the foci to prevent AF onset. Atrial wall motion characteristics (WMC) may be sensed using an accelerometer placed on the heart and used with MEA to detect AF. The WMC may be used to monitor effectiveness of the pacing signal in preventing AF and/or returning the heart to normal sinus rhythm (NSR). Also, upon AF detection, a cardioversion signal may be sent to the atria using the electrodes to depolorize an atrial area causing AF and return the heart to NSR.

The device provides a monitor having sensing, pacing, recording and transmission capabilities. At least two pacing electrodes are provided with adhesive backing for application to the anterior chest region with one cathode to the region of the cardiac apex and an anode to the region of the right upper sternal cardiac border. If a bradycardic episode is detected or prolongation of the QT is sufficient, then pacemaking energy is provided to the electrodes allowing the patient time to seek medical care without suffering the results of temporary hemodynamic instability that might otherwise be associated with dysrhythmia.

  • Patent number: 9910960
    Abstract: Methods and systems are presented for indicating the proximity of a process requirement metric to a corresponding system process requirement in a physiological monitor. Metrics are determined based on a received physiological signal, such as a PPG signal. At least one of the metrics is compared to a corresponding system process requirement, such as a threshold, which can be used to trigger a system process, such as an alarm, a recalibration, or a measurement. The proximity of the metric to the corresponding system process requirement is calculated and indicated. Indicating the proximity to a system process requirement may provide valuable information to clinicians and allow them to manually trigger system processes, such as measurements or recalibrations, when a metric is close to a system process requirement for a significant period of time.
