摘要： Embodiments of a wearable cardioverter defibrillator (WCD) system are configured to monitor a patient's ECG for shockable arrhythmias and deliver a shock to the patient in response to such a detection. To monitor the patient's ECG with reduced signal noise to improve the system's performance, the system includes a cable assembly having: a signal line; an inner shield and an outer shield; an ECG electrode electrically connected to the signal line of the cable assembly; and an amplifier having first and second input nodes respectively connected to the signal line and the outer shield of the cable assembly. The amplifier's output node is electrically connected to the inner shield of the cable assembly to reduce the reactive load seen by the patient's heart in driving the ECG sensing circuitry, which reduces the noise on the ECG signal outputted by the amplifier.

摘要： A WCD system is configured to monitor various characteristics of the WCD system including about the patient. The WCD system is further configured to transmit a notification of a notifiable event to responders that are outside a local area of the patient, and to silence the notification for any responder(s) that are inside the local area of the patient.

摘要： In one embodiment, a wearable cardioverter defibrillator (WCD) is described. The WCD includes a support structure worn by a patient. A processor is coupled to the support structure. The WCD also includes a discharge circuit coupled to an energy storage module, the discharge circuit configured to discharge the stored electrical charge through a body of the patient. The wearable cardioverter defibrillator also includes a user interface housing at least one sensor and responsive to changes in device orientation. The processor is configured to detect a motion at the user interface and determine when the motion is patient-activated. When the motion is patient-activated, the processor determines a direction of rotation. The processor determines an orientation of a display at the user interface based on the direction of rotation and orients the display at the user interface to appear upright to the patient.

摘要： A wearable cardioverter defibrillator (“WCD”) system may include an impedance detector configured to render an impedance signal of the patient. The WCD system may determine, from the impedance signal, a characteristic of breathing by the patient that can be used as a vital sign. The WCD system may determine, from at least the breathing characteristic, whether or not a shock criterion is met. If the shock criterion is met, the WCD system may control a discharge circuit to discharge a stored electrical charge through the patient. An advantage can be that the breathing characteristic may be used to determine whether or not a patient is experiencing a condition that requires defibrillation therapy, such as sudden cardiac arrest. Even more advantages can be had in discerning the state of the patient when the breathing characteristic is combined with other data, such as from a motion detector.

摘要： Apparatus and methods for generating pulse pacing in a wearable cardioverter defibrillator (“WCD”). In one aspect the WCD circuitry includes a power source such as a battery coupled to a charger that provides charge energy to an energy storage module. Control circuitry is operatively coupled to the charger and the output circuitry, and configured to cause the WCD circuitry to generate pacing pulses delivered to therapy electrodes (attached to an ambulatory patient) without a current source. The WCD circuitry includes one or more processing elements that are used to execute instructions provided by one or more software modules that are configured to support various functionality, including controlling generation of pacing pulses.

摘要： Embodiments of this disclosure are directed to a wearable cardioverter defibrillator (“WCD”) system design in which a WCD implements an alert prioritization scheme to provide the patient with feedback in an order that is less likely to cause confusion. Different conditions (e.g., device status, equipment condition, or physiologic condition) are prioritized based on an analysis of severity of the condition and timeliness of user action needed. The prioritization scheme defines what alert, if any, is presented to the user by the WCD system as a result of various conditions. Generally stated, an alert for the highest priority condition currently detected is presented to the user and maintained until that condition either changes or becomes surpassed in the prioritization scheme.

摘要： A wearable medical system (WMS) includes one or more pacing capabilities. The WMS May detect when the patient's heart rhythm starts to deteriorate, but not necessarily in a way that requires Defibrillation. In particular, the WMS may detect bradycardia of one or more types, and then confirm the detection before pacing to treat the detected bradycardia.

摘要： A Wearable Cardiac Defibrillator (WCD) system is configured to be worn by a patient who carries a mobile communication device. The mobile communication device has a user interface that is configured to enable the patient to enter wireless inputs. The WCD system includes a communication module that is configured to establish a local comlink with the mobile communication device. The WCD system also includes a tethered action unit that has a user interface configured to enable the patient to enter action inputs. The WCD system can perform some of its functions in response to the action inputs or to the wireless inputs. Since the wireless inputs can be provided from the mobile communication device instead of the action unit, the patient is less likely to attract attention when entering them, and thus exhibit better compliance.

摘要： A wearable cardiac defibrillator (“WCD”) system may include a support structure that a patient can wear, an energy storage module that can store an electrical charge, and a discharge circuit that can discharge the electrical charge through the patient so as to shock him or her, while the patient is wearing the support structure. Embodiments may actively take into account bystanders, both to protect them from an inadvertent shock, and also to enlist their help. In some embodiments the WCD system includes a speaker system that transmits a sound designed to assist a bystander to perform CPR. Optionally CPR chest compressions received by the patient can be further detected, and feedback can be given. In embodiments, a WCD system may include a user interface that can be controlled to output CPR prompts tailored to a skill level of the bystander.
