A personal wearable emergency medical treatment device, including: a first housing unit including an control unit for an automatic defibrillator device; at least two, and preferably three, electrodes in electrical communication with the housing unit; wherein the electrodes are adapted to be positioned in proximity to a human body at preselected positions selected for monitoring for heartbeat abnormalities and providing electric pulses to the human body.

A wearable therapeutic device is provided. The wearable therapeutic device includes a garment, and the garment includes an electrode and a conductive thread. A control unit is coupled to the conductive thread and identifies an electrical connection between a conductive surface of the electrode and the conductive thread, and an alarm module can provide information about the positioning of the electrode in the garment based on the electrical connection.

A variety of arrangements and methods relating to a defibrillator are described. In one aspect of the invention, a defibrillator includes two paddles that each include a defibrillator electrode covered in a protective housing. The two paddles are sealed together using a releasable seal to form a paddle module such that the housings of the paddles form the exterior of the paddle module. An electrical system including at least a battery and a capacitor is electrically coupled with the paddles. The battery is arranged to charge the capacitor. The capacitor is arranged to apply a voltage at the defibrillator electrodes, which generates an electrical shock for arresting a cardiac arrhythmia.

A method for performing CPR with a mobile defibrillator (AED) unit can include detecting, via an application on a user device, a connection of a mobile AED unit to the user device; detecting, via the application, that pads have been attached to a subject, the pads comprising at least one accelerometer; recording, via the application, EKG measurements of the subject made by the pads; receiving accelerometer data from the at least one accelerometer; analyzing the accelerometer data to determine a breathing pattern of the subject; and based on the determined breathing pattern, initiating a CPR protocol.

A wearable monitoring and therapeutic device includes at least two sensing electrodes. Each sensing electrode includes a metallic surface integrated in a garment. The device includes at least two therapy electrodes. Each of the at least two therapy electrodes includes a receptacle, and each receptacle includes at least one dose of conductive fluid. The device includes the garment. The garment includes a fabric that is stretchable and that is breathable and/or moisture wicking, and conductive wiring configured to at least partially electrically connect that at least two sensing electrodes to at least one defibrillator component. The device includes the at least one defibrillator component. The at least two therapy electrodes are configured to provide an electric shock to the subject. Prior to the application of the electric shock, each receptacle is configured to release the conductive fluid from the receptacle.

In embodiments, a Wearable Cardioverter Defibrillator (WCD) system includes a support structure for the patient to wear, and components that the support structure maintains on the patient's body. The components include a defibrillator, associated electrodes, and so on. The defibrillator can operate in a WCD mode while the patient wears the support structure. The defibrillator can further operate in a different, AED mode, during which time the patient need not wear a portion of the support structure, or even the entire support structure. Sometimes the AED mode is a type of a fully automatic AED mode. Other times the AED mode is a type of a semi-automated AED mode, where an attendant is present to administer the shock; at such times, the patient may not even need to have electrodes attached. This way the patient is more comfortable for a longer time.

A wearable therapeutic device is provided. The wearable therapeutic device includes a garment, and the garment includes an electrode and a conductive thread. A control unit is coupled to the conductive thread and identifies an electrical connection between a conductive surface of the electrode and the conductive thread, and an alarm module can provide information about the positioning of the electrode in the garment based on the electrical connection.

An implantable medical device system is configured to detect a tachyarrhythmia from a cardiac electrical signal and start an ATP therapy delay period. The implantable medical device determines whether the cardiac electrical signal received during the ATP therapy delay period satisfies ATP delivery criteria. A therapy delivery module is controlled to cancel the delayed ATP therapy if the ATP delivery criteria are not met and deliver the delayed ATP therapy if the ATP delivery criteria are met.

Implantable medical electrical leads having electrodes arranged such that a defibrillation coil electrode and a pace/sense electrode(s) are concurrently positioned substantially over the ventricle when implanted as described. The leads include an elongated lead body having a distal portion and a proximal end, a connector at the proximal end of the lead body, a defibrillation electrode located along the distal portion of the lead body, wherein the defibrillation electrode includes a first electrode segment and a second electrode segment proximal to the first electrode segment by a distance. The leads may include at least one pace/sense electrode, which in some instances, is located between the first defibrillation electrode segment and the second defibrillation electrode segment.

A medical apparatus provides resuscitative therapy to a patient. The apparatus includes an electrocardiogram (ECG) input, a defibrillation output configured to provide an electrical defibrillation shock treatment, and an applicator body configured to provide active compression decompression therapy to the patient's chest. The applicator body includes a rescuer end configured for hands of the rescuer to press and pull on the applicator body, a coupling surface configured to adhere to the patient's chest to provide active compression decompression therapy, a capacitor, and processor(s) configured to receive and analyze the ECG signal of the patient, determine whether the patient is in need of defibrillation, and administer the defibrillation shock treatment to the patient.
