A temporary pacing lead device comprises: an elongate body having a distal portion and a proximal end; an electrode array at the distal portion configured to deliver a pacing signal to target tissue; a displacement member attached to a first side of the distal portion; at least one anchoring element deployable from a second opposite side; and an interface at the proximal end of the elongate body. The interface is configured to couple to a pacing signal generator and/or a control handle to actuate the displacement member and/or anchoring element. The pacing generator can be a miniature pacing signal generator and/or a standard pacemaker device, and the interface can switch between providing the pacing signal from either of the two sources. The miniature pacing signal generator can include a protective element for the control and/or actuation elements at the proximal end.

An external defibrillator system for assisting manual delivery of chest compressions and ventilations to a patient by a rescuer as cardiopulmonary resuscitation (CPR) includes a speaker, and a processor, memory, and associated circuitry coupled to the speaker. The processor is configured to initiate prompting for the chest compressions and the ventilations manually delivered to the patient by the rescuer as CPR, control the speaker to generate first auditory cues for the chest compressions, and control the speaker to generate second auditory cues for the ventilations with a different sound than the first auditory cues for the chest compressions. The first auditory cues and the second auditory cues assist the rescuer in timing the delivery of the chest compressions and the ventilations.

A medical device that includes a power source, a therapy delivery interface, therapy electrodes, electrocardiogram (ECG) sensing electrodes to sense ECG signal of a heart of a patient, a sensor interface to receive and digitize the ECG signal, and a processor. The processor is configured to analyze the ECG signal to determine a cardiac rhythm and a transform value representing a magnitude of a frequency component of the cardiac rhythm, analyze the cardiac rhythm and the transform value to detect a shockable cardiac arrhythmia by classifying the cardiac rhythm as a noise rhythm or a shockable cardiac arrhythmia rhythm based on the transform value, and causing the processor to detect the cardiac arrhythmia if classifying the cardiac rhythm as a shockable cardiac arrhythmia rhythm, initiate a treatment alarm sequence, adjust the shock delivery parameter for a defibrillation shock, and provide the defibrillation shock via the therapy electrodes.

Techniques are described for pacing assistance and automation. For example, a pacing device, such as an external defibrillator, provides electrical stimulations to an external surface of a patient based on a determination as to whether capture has been achieved. The pacing device determines whether capture has been achieved using multiple types of sensor data and/or historical sensor data. These techniques effect a particular treatment (e.g., pacing using an external pacing system) for a medical condition (e.g., bradycardia). In some examples, the pacing device provides notifications to assist with pacing to a healthcare provider that is administering pacing to a patient. Notifications may include an indication that multiple representations corresponding to different biological parameters of a patient may assist with pacing, that the patient has an internal pacemaker, and so forth.

The invention relates to improvements in the technical field of external electromedical pulse generators. For this purpose, it is proposed in the case of an electromedical pulse generator that it has an electronics module and a control module separate therefrom, which can be used spatially separated from one another when the electromedical pulse generator is used.

An ambulatory cardiac device for improving a signal to noise profile of an electrocardiogram (ECG) signal of a patient is provided. The ambulatory cardiac device includes a plurality of active ECG electrodes disposed in a plurality of locations about a patient. Each active electrode can include an ECG electrode substrate configured to be in physical contact with skin of the patient, a local biasing substrate proximate to the ECG electrode substrate and configured to be in physical contact with the skin of the patient, and local biasing circuitry configured to provide a local biasing signal into a body of the patient via the local biasing substrate.

The disclosure provides systems and methods for detecting, monitoring, and/or treating obstructive sleep apnea, as well as other conditions, using vital sign and/or biometric data collected and/or imputed from one or more photoplethysmography sensors in conjunction with vital sign and/or biometric data from one or more additional sensors such as activity, body position, ECG, HR, or SpO.sub.2 levels, e.g., as feedback to control therapy and/or to titrate therapy on a periodic basis.

Systems and methods for treating diseases and disorders in a patient are provided. A device comprises a stimulator comprising an electrode and an energy source. The energy source is configured to generate an electrical impulse and transmit the electrical impulse to the electrode through an outer skin surface to a vagus nerve of the patient. The device further comprises a sensor for detecting a physiological parameter of a patient's heart and a controller coupled to the stimulator and the sensor and configured to activate the stimulator based on the physiological parameter to cause the stimulator to generate the electrical impulse. In some aspects, the electrical impulse is sufficient to modulate the vagus nerve to treat a cardiac arrhythmia of the patient.

A medical device of the type used for assisting a user in manually delivering repetitive therapy to a patient (e.g., chest compressions or ventilations in cardiac resuscitation), the device comprising a feedback device configured to generate feedback cues to assist the user in timing the delivery of the repetitive therapy, at least one sensor or circuit element configured to detect actual delivery times, at which the user actually delivers the repetitive therapy, and a processor, memory, and associated circuitry configured to compare the actual delivery times to information representative of desired delivery times to determine cue times at which the feedback cues are generated by the feedback device.

An electrode for long term wear can include a top layer. The top layer includes a non-conductive, flexible, water vapor-permeable, electrically-insulating material. The electrode also includes a conductive adhesive material and at least one electrical connector configured to connect the electrode to a wearable defibrillator such that the electrode is configured to receive defibrillation energy from the wearable defibrillator and provide a sensing function for the wearable defibrillator. The conductive adhesive material is configured to disperse current laterally along a plane of a surface of the electrode prior to delivery of the defibrillation energy.
