Detecting Heartbeat Electric Signal And Diverse Cardiovascular Characteristic Patents (Class 600/513)
  • Patent number: 10736521
    Abstract: A method of monitoring and/or diagnosing an autoregulation mechanism of blood pressure of a living being using an ECG signal includes recording the ECG signal of the living being, and the recording a pulse wave curve synchronously with the recording of the ECG signal. Heart rate intervals are determined from the ECG signal. A pulse wave transit time is determined for each heart rate interval from the pulse wave curve. A plurality of significant changes in the pulse wave transit times are determined according to a specified criterion. One respective heart rate interval correlated in time with each significant change in the pulse wave transit times is selected as an anchor point. A determined limited number of temporally successive heart rate intervals temporally before and/or after each anchor point are selected to thus generate a limited sequence of heart rate intervals for each anchor point.

  • Patent number: 10667711
    Abstract: Physiological monitoring can be provided through a wearable monitor that includes two components, a flexible extended wear electrode patch and a removable reusable monitor recorder. The wearable monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline (or immediately to either side of the sternum) benefits extended wear by removing the requirement that ECG electrodes be continually placed in the same spots on the skin throughout the monitoring period. The wearable monitor can interoperate wirelessly with other physiology and activity sensors and mobile devices, and can include cellular phone capabilities. The power usage of the wireless communication can be reduced by using a low energy wireless transceiver in the monitor. The monitor detects that the monitor has been adhered to the patient and begin collecting physiological data after such detection, preserving battery power.

  • Patent number: 10456053
    Abstract: A wrist worn heart rate monitor includes a photoplethysmogram (PPG) sensor and an inertial sensor. Signals from the inertial sensor are used to identify and remove noise from the PPG signals. An initial heart rate value is selected from a number of heart rate candidates that remain in the resulting PPG spectrum and is used to track the heart rate of the user. The PPG spectrum is monitored while tracking the heart rate to determine if the selected initial heart rate value is in error. The PPG spectrum may be monitored by determining a correlation of possible heart rate candidates in each PPG spectrum to the previous heart rate candidates and resetting the heart rate value accordingly. Additionally or alternatively, the PPG spectrum may be monitored by determining when only a single heart rate candidate is present in consecutive PPG spectra and resetting the heart rate value accordingly.

  • Patent number: 10441798
    Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

  • Patent number: 10058709
    Abstract: An automated external defibrillation (AED) device includes a wireless interface to exchange data with one or more other devices. The AED device collects patient data associated with a patient and identifies, based on the patient data, a heart condition associated with the patient. The AED device directs a user to apply defibrillation to the patient to address the heart condition; and forwards via the wireless interface, a notification to a dispatch device. The notification may identify, for example, a location associated with the AED device. The dispatch device may direct emergency medical assistance to the location. The AED device may collect data, used to diagnose the heart condition, from a patient device and via the wireless interface. The AED device may further forward, to a user device and via the wireless interface, instructions guiding the user to use the AED device.

  • Patent number: 10062456
    Abstract: A risk-based patient monitoring system for critical care patients combines data from multiple sources to assess the current and the future risks to the patient, thereby enabling providers to review a current patient risk profile and to continuously track a clinical trajectory. A physiology observer module in the system utilizes multiple measurements to estimate Probability Density Functions (PDF) of a number of Internal State Variables (ISVs) that describe a components of the physiology relevant to the patient treatment and condition. A clinical trajectory interpreter module in the system utilizes the estimated PDFs of ISVs to identify under which probable patient states the patient can be currently categorized and assign a probability value that the patient will be in each of the identified states. The combination of patient states and their probabilities is defined as the clinical risk to the patient.

  • Patent number: 10028677
    Abstract: Quantitatively diagnosing ischemia by non-invasively sensing mechanical vibrations from mechanical contraction of a ventricle to measure a time duration of an isovolumetric contraction and a peak endocardial acceleration (PEA) of the heart during the IVCT and calculating a myocardial contractility index (MCI) of the subject, for example MCI=PEA/IVCT. Comparing the MCI of the subject during the sensing period to a baseline MCI which is defined as the baseline MCI of the subject or a representative value of the baseline MCI of a population of subjects less a predetermined value, and then determining by a processor whether the MCI of the subject declined during the sensing period by at least a predetermined amount relative to the baseline MCI. Also allows determination of an amount of viable myocardium, existence of total occlusion of a coronary artery, myocardial infarction and whether thrombolysis has been effective so as to be discontinued.

    Abstract: Systems and methods are provided to detect a multi-domain ECG waveform and display one or more cardiac electrophysiological markers. Electrical impulses are detected between at least one pair of electrodes adapted to be located near a beating heart and are converted to an ECG waveform. The ECG waveform for at least one heartbeat is received from the detector, the ECG waveform is converted to a frequency domain waveform, the frequency domain waveform is separated into two or more different frequency domain waveforms using two or more different bandpass filters, and the two or more different frequency domain waveforms are converted into two or more different time domain waveforms. The two or more different time domain waveforms are displayed in the same time domain plot as the ECG waveform and one or more cardiac electrophysiological markers are displayed along the x-axis of the two or more different time domain waveforms.

  • Patent number: 9986921
    Abstract: A real-time arrhythmia discrimination method is used in smartphones, which can discriminate between NSR, AF, PACs and PVCs using pulsatile time series collected from a smartphone's camera. To increase the sensitivity of AF detection and add the new capabilities of PVC and PAC identification, the arrhythmia discrimination method of these teachings combines Root Mean Square of Successive RR Differences (RMSSD), Shannon Entropy (ShE) and turning point ratio (TPR), with the Poincare plot, and utilizes the features of pulse rise/fall time and amplitude for arrhythmia discrimination.
