摘要： A wearable medical device is provided for monitoring the cardiac health of a patient, for example, for indications of cardiac anomalies, where the device includes ECG sensors in electrical contact with the patient's body, therapy electrodes for providing electrical therapy to the patient's heart, and a control unit having at least one touch control with force sensor disposed on its housing for contacting with a finger. Signals from the touch control may be analyzed to identify force application below a first force threshold and at or above a second force threshold below the first force threshold, and, responsive to detecting such application of force, user input may be registered. User inputs to the at least one touch control may be used to delay therapy by the therapy electrodes.

摘要： An apparatus for treating a person having cardiac arrest includes a processor and a lead in communication with the processor, the lead being configured to receive a segment of electrocardiogram (ECG) data from the person while undergoing cardiopulmonary resuscitation (CPR). The apparatus also includes a non-transitory computer-readable medium having: a first Convolutional Neural Network-based Encoder-Decoder (CNNED) structure to reduce artifacts due to the CPR; a second CNNED structure cascaded with the first CNNED structure to further reduce artifacts; and instructions to determine a first arrhythmia classification using the first CNNED structure, determine a second arrhythmia classification using the second CNNED structure in response to the first arrhythmia classification indicating a shockable arrhythmia event; and transmit a signal to apply a defibrillation shock to the person in response to the first arrhythmia classification and the second arrhythmia classification indicating a shockable arrhythmia of the person.

摘要： Disclosed herein are implantable medical devices and systems, and methods for used therewith, that selectively perform atrial overdrive pacing while an intrinsic atrial rate of a patient is within a specified range. Such a method can involve measuring intervals between a plurality of intrinsic atrial depolarizations that occur during a specified period, and classifying intrinsic atrial activity as stable or unstable based on the measured intervals. In response to classifying the intrinsic atrial activity as stable, atrial overdrive pacing is performed. In response to classifying the intrinsic atrial rate as unstable, atrial overdrive pacing is not performed (i.e., is abstained from being performed). Over time, effectiveness of performing atrial overdrive pacing using various different atrial interval shorting deltas are recorded in a log and updated, and the log is used to determine a preferred rate at which to perform atrial overdrive pacing for various different measured intervals.

摘要： A medical device is configured to detect an atrial tachyarrhythmia episode. The device senses a cardiac signal, identifies R-waves in the cardiac signal attendant ventricular depolarizations and determines classification factors from the R-waves identified over a predetermined time period. The device classifies the predetermined time period as one of unclassified, atrial tachyarrhythmia and non-atrial tachyarrhythmia by comparing the determined classification factors to classification criteria. A classification criterion is adjusted from a first classification criterion to a second classification criterion after at least one time period being classified as atrial tachyarrhythmia. An atrial tachyarrhythmia episode is detected by the device in response to at least one subsequent time period being classified as atrial tachyarrhythmia based on the adjusted classification criterion.

摘要： Implantable medical devices (IMD), such as but not limited to leadless cardiac pacemakers (LCP), subcutaneous implantable cardioverter defibrillators (SICD), transvenous implantable cardioverter defibrillators, neuro-stimulators (NS), implantable monitors (IM), may be configured to communicate with each other. In some cases, a first IMD may transmit instructions to a second IMD. In order to improve the chances of a successfully received transmission, the first IMD may transmit the instructions several times during a particular time frame, such as during a single heartbeat. If the second IMD receives the message more than once, the second IMD recognizes that the messages were redundant and acts accordingly.

摘要： 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. This architecture takes advantage of the nearly ubiquitous availability of smart phones, tablet computers and other mobile communication devices.

摘要： In some examples, processing circuitry of a medical device system determines, for each of a plurality of patient parameters, a difference metric for a current period based on a value of a patient parameter determined for the current period and a value of the patient parameter determined for an immediately preceding period, and determines a score for the current period based on a sum of the difference metrics for at least some of the plurality of patient parameters. The processing circuitry determines a threshold for the current period based on scores determined for N periods that precede the current period, compares the score for the current period to the threshold, and determines whether to generate an alert indicating that an acute cardiac event of the patient, e.g., ventricular tachyarrhythmia, is predicted, and/or deliver a therapy configured to prevent the acute cardiac event, based on the comparison.
