  • Patent number: 10646130
    Abstract: An ECG system measures and annotates the P-point of an ECG waveform from harmonic waveforms. Electrical impulses are received from a beating heart. The electrical impulses are converted to an ECG waveform. The ECG waveform is converted to a frequency domain waveform, which, in turn, is separated into two or more different frequency domain waveforms, which, in turn, are converted into a plurality of time domain cardiac electrophysiological subwaveforms and discontinuity points between these subwaveforms. The plurality of subwaveforms and discontinuity points are compared to a database of subwaveforms and discontinuity points for normal and abnormal patients. A discontinuity point is identified as the P-point of the ECG waveform from the comparison. Similar measurements are made for the P?-point, I-point, J-point, and T?-point. Distances from these points to the equipotential line are calculated and used to detect blockages leading to myocardial infarction.

  • Patent number: 10524697
    Abstract: System and method for monitoring motor recovery in a post-stroke treatment is disclosed. Motor activity data corresponding to limbs movement is collected during an acute stroke period. The motor activity data is transmitted to at least one base station and an activity value for each arm of two arms is calculated in a predefined time window by using the motor activity data. The activity value for each arm is compared thus providing the monitoring of the motor activity.

  • Patent number: 10517497
    Abstract: A system for processing ECG to detect atrial fibrillation includes three software modules. A beat module is executable on a processor to receive a time series of ECG data, identify heart beats, and determine a beat AFIB value based on a timing of each identified heart beat. The beat AFIB value represents a presence or absence of AFIB based on variability in the timing of each identified heart beat. A segment module is executable to receive the time series of ECG data, divide the time series of ECG data into two or more time segments, and determine a segment AFIB value for each time segment. The segment AFIB value indicates a presence or absence of AFIB in the time segment based on whether any of a set of rhythms are identified. The AFIB detection module is executable to determine an AFIB identification value for each time segment based on the beat AFIB value during that time segment and the segment AFIB value for that time segment.

  • Patent number: 10507331
    Abstract: In embodiments, a wearable cardiac defibrillator system includes an energy storage module configured to store a charge. Two electrodes can be configured to be applied to respective locations of a patient. One or more reservoirs can store one or more conductive fluids. Respective fluid deploying mechanisms can be configured to cause the fluids to be released from one or more of the reservoirs, which decreases the impedance at the patient location, and decreases discomfort for the patient. In some embodiments an impedance is sensed between the two electrodes, and the stored charge is delivered when the sensed impedance meets a discharge condition. In some embodiments, different fluids are released for different patient treatments. In some embodiments, fluid release is controlled to be in at least two doses, with an intervening pause.

  • Patent number: 10506946
    Abstract: Methods, systems, and apparatuses for visualizing the motion box of an electromagnetic sensor tracking system on a display that can be viewed by the physician are disclosed. Electromagnetic sensor tracking systems are able to determine the position and orientation (P&O) of the sensors being tracked only when the sensors are within the motion box, or the spatial region located in proximity to the electromagnetic field generators of the system. During usage of the electromagnetic sensor tracking system, the sensor can go out of this spatial region and, when this occurs, navigating it back into the motion box can be difficult. The methods, systems, and apparatuses described herein provide for the representation of sensors, the motion box, and a representation of a thorax on a display so that the clinician can view the position and orientation of the sensors with respect to the motion box.

  • Patent number: 10510444
    Abstract: Techniques for administering a care plan. Embodiments receive the care plan specifying observation metrics to monitor biometric data collected from a patient. At least one monitoring device available is identified and embodiments receive biometric data collected using the at least one monitoring device, where the biometric data is initially classified as a first type of event by the at least one monitoring device. Additionally, embodiments analyze the received biometric data to reclassify the first event as an occurrence of a second type of even, and, upon determining that the occurrence of the second type of event satisfies at least one threshold condition specified in the care plan, initiate at least one treatment plan specified in the care plan and corresponding to the satisfied at least one threshold value.

  • Patent number: 10499825
    Abstract: An ECG monitoring system for ambulatory patients includes a disposable multi-electrode patch that adhesively attaches to the chest of a patient. A reusable battery-powered ECG monitor clips onto the patch and receives patient electrical signals from the electrodes of the patch. A processor continuously processes received ECG signals and stores the signals in memory in the monitor. The processor also analyzes the received ECG signals for predefined arrhythmia. If an arrhythmia is detected, a bi-directional wireless transceiver in the ECG monitor transmits the event information and an ECG strip to a cellphone handset. The cellphone handset automatically relays the event information and ECG strip to a monitoring center for further diagnosis and necessary intervention.
