US 2026/0257073 A1 · ELECTRODE PLACEMENT VERIFICATION SYSTEM

Abstract

A wearable cardiac device includes a garment configured to be worn on a torso of the ambulatory patient and has one or more therapy electrode pockets. The device may also include a plurality of ECG sensing electrodes configured to sense ECG signals of the ambulatory patient, a plurality of therapy electrodes configured to deliver one or more therapeutic shocks to the ambulatory patient, and a plurality of anatomical placement accelerometers. A controller in electrical communication with the plurality of electrodes and the plurality of anatomical placement accelerometers can be configured to determine, based on received anatomical placement motion signals, at least one of (a) a facing orientation of the plurality of therapy electrodes, or (b) a relative position of each therapy electrode relative to another therapy electrode of the plurality of therapy electrodes, and generate an improper electrode placement in garment alert for the patient.

Dependent claims

A wearable cardiac device configured for placement verification of electrodes in a garment worn by an ambulatory patient, the device comprising:

the garment configured to be worn on a torso of the ambulatory patient, the garment comprising one or more therapy electrode pockets configured to align with one or more predetermined anatomical locations on the ambulatory patient;
a plurality of ECG sensing electrodes configured to sense ECG signals of the ambulatory patient, wherein the plurality of ECG sensing electrodes are configured to be disposed at one or more predetermined ECG sensing locations within the garment;
a plurality of therapy electrodes configured to deliver one or more therapeutic shocks to the ambulatory patient, wherein each therapy electrode of the plurality of therapy electrodes is configured to be disposed within a therapy electrode pocket of the one or more therapy electrode pockets of the garment;
a plurality of anatomical placement accelerometers, wherein each anatomical placement accelerometer is integrated with a corresponding therapy electrode of the plurality of therapy electrodes and configured to generate an anatomical placement motion signal for the corresponding therapy electrode;
and
a controller in electrical communication with the plurality of electrodes and the plurality of anatomical placement accelerometers, the controller configured to
receive anatomical placement motion signals from the plurality of anatomical placement accelerometers,
determine, based on the received anatomical placement motion signals, at least one of
(a) a facing orientation of the plurality of therapy electrodes, or
(b) a relative position of each therapy electrode relative to another therapy electrode of the plurality of therapy electrodes,
generate, responsive to a determination that the at least one of a facing orientation of the plurality of therapy electrodes or a relative position of each therapy electrode relative to another therapy electrode of the plurality of therapy electrodes does not meet a predetermined electrode placement criterion relating to proper placement of the electrodes within the garment, an improper electrode placement in garment alert for the patient, and
provide the generated improper electrode placement in garment alert to the patient.

A wearable cardiac device configured for placement verification of electrodes on an ambulatory patient, the device comprising:

a garment configured to be worn on a torso of the ambulatory patient, the garment comprising one or more garment attachment features aligned with one or more anatomical locations on a patient;
a plurality of electrodes configured to one of sense ECG signals of a patient or deliver one or more therapeutic shocks to the patient, wherein each electrode of the plurality of electrodes is configured to be removably coupled to the garment at the one or more anatomical locations on the ambulatory patient via the one or more garment attachment features;
at least one anatomical placement sensor circuit associated with at least one of the plurality of electrodes and configured to generate at least one anatomical placement motion signal associated with the at least one of the plurality of electrodes;
and
a controller in electrical communication with the plurality of electrodes and the at least one anatomical placement sensor circuit, the controller configured to
receive the generated at least one anatomical placement motion signal from the at least one anatomical placement sensor circuit;
determine, based on the received at least one anatomical placement motion signal, an anatomical placement of the associated at least one of the plurality of electrodes;
generate, responsive to a determination that the anatomical placement of the associated at least one of the plurality of electrodes does not meet an anatomical placement condition comprising a location and orientation of the plurality of electrodes within the garment, an improper electrode placement in garment alert for the patient;
and
provide the generated improper electrode placement in garment alert to the patient.
