Methods and systems of evaluating cardiac pacing in candidate patients for cardiac resynchronization therapy and cardiac resynchronization therapy patients are disclosed. The methods and systems disclosed allow treatments to be personalized to patients by measuring the extent of tissue capture from cardiac pacing under various therapy parameter conditions. Systems and methods of optimizing right ventricle only cardiac pacing are also disclosed.

Systems, devices and methods for advanced electrode management in neurological monitoring applications include receiving sockets configured to receive connectors having groups of electrodes. The physician is not required to manually map each electrode with its corresponding input channel. Electrodes are coupled to the corresponding input channels in groups through connectors having a unique identification (ID). The system is configured to read the unique ID of each connector and establish its identity. Based on the ID, the system configures itself to automatically correlate or associate each electrode with its corresponding input channel when the connectors are first inserted into the receiving sockets, and again if the connectors are removed and re-inserted into different positions in the receiving sockets, to insure the electrodes are always mapped to the same input channels.

An attention mechanism-based 12-lead electrocardiogram (ECG) classification method is described, the method including acquiring an original image of a 12-lead ECG, segmenting waveform data recorded in the original image to obtain segmented waveform data for each lead in the 12-lead ECG, performing depth feature extraction on the segmented waveform data of said each lead to obtain a first feature map of said each lead, performing feature transformation on the first feature map of said each lead based on an attention mechanism to obtain a depth feature of said each lead, and classifying the depth feature of said each lead to obtain a classification result for the original image. The classification method can make full use of the 12-lead ECG for overall classification and improve the accuracy of image classification.

An electrocardiogram system is provided. The system includes an array of sensors configured to generate electrical signals relating to cardiac activity. The system further includes a plurality of lead cables. Each lead cable includes a sensor terminal, an opposing sensor terminal, and an intermediate segment. The intermediate segment is interposed between the sensor terminal and the opposing sensor terminal. The array of sensors are electrically coupled to the sensor terminals. The intermediate segment is configured to carry the electrical signals from the sensor terminal to the opposing sensor terminal. The intermediate segment is enclosed by a non-conductive enclosure. The non-conductive enclosure having opposing linear surfaces and opposing lateral surfaces extending from the opposing linear surfaces. The opposing linear surfaces are parallel with respect to each other.

A wearable device configured to measure one or more physiological parameters of a user is described. In some embodiments, the wearable device includes: a top frame, a bottom frame connected to the top frame, and an interior between the top and bottom frames; a circuit board positioned within the interior; a first temperature sensor coupled to the circuit board and configured to generate one or more signals responsive to thermal energy of the user; and a second temperature sensor coupled to the circuit board and configured to generate one or more signals responsive to at least one of temperature within said interior and temperature outside said interior. In some embodiments, the circuit board is positioned between the first and second temperature sensors and no air gap is present between either of the first and second temperatures and the circuit board.

A electrocardiogram (EKG) lead attachment with a visual aid device including a plurality of retractable leads, a housing member, a plurality of label designations, a plurality of label designation tags, a lead placement visual aid, and a plurality of color tags. The lead placement visual aid includes an anatomical image of a chest cavity including color coordinated label designations which are each positioned on the anatomical image at a location where a corresponding lead in the first set should be placed on the human body. The plurality of color tags are coordinated to match the colors of the color coordinated label designations in the visual aid. The color designations and tags are used to provide an easy to follow visual aid to an operator for placement of the leads on a human body.

A wearable diagnostic electrocardiogram (ECG) garment is disclosed herein. The wearable diagnostic ECG garment comprises a garment body, screen-printed electrodes positioned on the body, and screen-printed wires positioned in the garment body, each of the screen-printed wires connected from a central connector module to a screen-printed electrode.

Systems and methods are described herein related to the evaluation and adjustment of left bundle branch (LBB) pacing therapy. Evaluation of the LBB pacing therapy may utilize electrical activity monitored from a plurality of external electrodes. The electrical activity may be used to provided one or more metrics of dispersion of surrogate cardiac electrical activation times, which may then be used to evaluate, and potentially adjust the LBB pacing therapy.

Devices, systems, and methods herein relate to electromyography (EMG) that may be used in diagnostic and/or therapeutic applications, including but not limited to electrophysiological study of muscles in the body relating to neuromuscular function and/or disorders. Sensor assemblies and methods are described herein for non-invasively generating an EMG signal corresponding to muscle tissue where the sensor may be positioned directly on a surface of the muscle tissue including any associated membrane (e.g., mucosal, endothelial, synovial) overlying the muscle tissue. A sensor assembly may include one or more pairs of closely spaced, atraumatic electrodes in a bipolar or multipolar configuration. The first and second electrodes may be applied against a surface of muscle tissue (that may include a membrane overlying the muscle) and receive electrical activity signal data corresponding to an electrical potential difference of the portion of muscle between the electrodes.
