  • Patent number: 10799135
    Abstract: A computer Implemented method and system for detecting arrhythmias in cardiac activity are provided. The method is under control of one or more processors configured with specific executable instructions. The method obtains far field cardiac activity (CA) signals and applies a direction related responsiveness (DRR) filter to the CA signals to produce DRR filtered signals. The method compares a current sample from the CA signals to a prior sample from the DRR filtered signals to identify a direction characteristic of the CA signals and defines the DRR filter based on a timing constant that is set based on the direction characteristic identified. The method analyzes the CA signals in connection with the DRR filtered signals to identify a peak characteristic of the CA signals and determines peak to peak intervals between successive peak characteristic. The method detects at least one of noise or an arrhythmia based on the peak to peak intervals and records results of the detecting.

  • Patent number: 10549108
    Abstract: A method for extinguishing a cardiac arrhythmia utilizes destructive interference of the passing of the reentry wave tip of an anatomical reentry through a depolarized region created by a relatively low voltage electric field in such a way as to effectively unpin the anatomical reentry. Preferably, the relatively low voltage electric field is defined by at least one unpinning shock(s) that are lower than an expected lower limit of vulnerability as established, for example, by a defibrillation threshold test. By understanding the physics of the electric field distribution between cardiac cells, the method permits the delivery of an electric field sufficient to unpin the core of the anatomical reentry, whether the precise or estimated location of the reentry is known or unknown and without the risk of inducting ventricular fibrillation. A number of embodiments for performing the method are disclosed.

Notably, the exemplified system minimizes non-linear distortions (e.g., those that can be introduced via certain filters) in the acquired wide-band phase gradient signal so as to not affect the information therein.

  • Patent number: 10537746
    Abstract: An automated external defibrillator (AED) is described which spends an increased proportion of a rescue in a CPR mode. This is accomplished by use of a single shock protocol which causes the AED to spend less time in shock analysis and delivery activities as compared with the typical multiple shock protocol. An AED of the present invention preferably is configured such that the rescue protocol can be modified or changed easily without the need to remove the battery or use specialized hardware or software. Preferably the shock waveform of the single shock is a biphasic waveform delivering at least 150 Joules of energy and more preferably at least 200 Joules of energy.

  • Patent number: 10500403
    Abstract: A wearable cardioverter defibrillator (“WCD”) system may output a loud sound after detecting and validating a shockable cardiac arrhythmia. In such embodiments, however, the WCD system might not sound a loud alarm before validating the arrhythmia thoroughly, i.e. for a longer time, thus giving the arrhythmia a further chance to self-terminate. The WCD system may thus detect more robustly the cardiac arrhythmias that do not self-terminate quickly. Such arrhythmias that self-terminate quickly may occur from likely harmless events occurring multiple times in the daily life of the patient, such as the patient becoming “winded” from climbing stairs. In embodiments the WCD system may notify the patient only discreetly, or even not at all. The lack of sounding such a loud alarm responsive to such events reduces the overall number of times in which the patient experiences unwanted attention by others, embarrassment, loss of privacy and dignity, and so on.

  • Patent number: 10490308
    Abstract: Devices, systems, software and methods for CPR quality assessment. Patient data is received that may be derived from a session of administering sets of CPR chest compressions to a patient. The sets can be separated by pauses. Then a figure of merit (FOM) can be computed from the data. In the computation, at least one pause can contribute a penalty to the FOM. The penalty has a value determined from at least one control factor, other than a constant linear dependence on the duration of the pause. This way, pauses can incur penalties to the FOM computation depending on their context, instead of merely their duration. For example, a penalty can escalate non-linearly if its pause becomes unduly long, or if it follows a set of chest compressions that was unduly short. As such, a better CPR quality assessment is achieved.

  • Patent number: 10449380
    Abstract: Several defibrillators, defibrillator architectures, defibrillator components and methods of operating defibrillators are described. In one aspect, a defibrillator (as for example an automated external defibrillator) that can be powered by a mobile communication device such as a smart cellular phone or a tablet computer is described. Utilizing a phone (or other mobile communication device) as the power supply for an external defibrillator allows the external defibrillator to be smaller and, in some circumstance, removes the need for a battery that stores sufficient energy for shock delivery—which would need to be checked and/or replaced on a regular basis. Additionally, when desired, certain control functionality, computation, data processing, and user instructions can be handled/presented by the mobile communications device thereby further simplifying the defibrillator design and improving the user experience.

  • Patent number: 10449379
    Abstract: An automated external defibrillator (“AED”) (10) employing a self-test circuit (11) and an encoded status indicator. The self-test circuit (11) automatically tests AED (10) and dependent upon the tests, generates both a base status signal (110) indicative of an operational readiness of AED (10) and a test status signal (120) indicative of self-test information of AED (10). The encoded status indicator concurrently visually indicates both the base status signal (110) and the test status signal (120) with the visual indication of the base status signal (110) being perceivable to a human eye and the visual indication of the test status signal (120) being unperceivable to the human eye. The encoded status indicator may employ a light source (14) for emitting a status light (20) and an encoder (13) to intensity modulate the status light (20) as emitted by the light source (14) as a function of an encoding of the base status signal (110) and the test status signal (120) by the encoder (13).
