摘要:
A system (140) and method (270) for ECG data (166) classification for use in facilitating diagnosis of cardiac rhythm disorders is provided. ECG data (166) is obtained via an electrocardiography monitor (212) with a patient button (255). A press of the patient button (255) is identified within the ECG data (166). A button window with a segment of data prior to and after the button press is defined (322) within the ECG data (166). The ECG data (166) is divided into blocks. Noise detection analysis is applied to the data blocks. A classification of noise or valid data is assigned (293) to each data block based on the noise detection analysis (290). At least one data block that overlaps (324) the button window is assigned (317) the noise classification. The at least one data block is trimmed (325) to align with one of the start and end of the button window. The trimmed blocks assigned with the noise classification are removed (326) from the data.
摘要:
An insertable cardiac monitor (ICM) with induction-based recharging capabilities and a transmitting coil for recharging the same are disclosed. The length of the monitoring performed by the ICM is extended and the functionality of the ICM enhanced, by including an internal energy harvesting module that allows for charging the ICM at a high speed without burning the patient or overheating components of the ICM. Internally, the energy harvesting module includes at least two overlapping receiving coils that are spaced to be orthogonal to each other and that have a tilt angle of substantially 45°. Such overlapping wire combination allows to minimize mutual inductance of the solenoid coils and increase the rate at which energy can be provided to the energy harvesting module. Further, the rate at which the energy is transmitted from the outside can be increased by defining in a transmitting coil a substantially triangular gap.

A system (320) and method for remote ECG data streaming in real-time is provided. ECG data is encrypted on a physiological monitor (322) placed on a patient (321) via a near-field communication chip on the physiological monitor (322). A continuous connection is established between the physiological monitor (322) and a cloud-based server (326) via a wireless transceiver on the physiological monitor (322). The encrypted ECG data is transmitted from the physiological monitor (322) to the cloud-based server (326). The ECG data is then transmitted from the cloud-based server (326) to a device (327) associated with a medical professional in real-time.
摘要:
A wearable electrocardiography monitoring ensemble (300) is provided, which includes a garment (301) made of a compressible and elastomeric material. The garment (301) is wearable about an upper region of the torso (305) and further includes an internal structure (302) forming a compressive bias circumferential to the torso (305). The ensemble (300) also includes an electrode assembly (313) provided on an inside surface of the garment (301) on an underside of the internal structure (302). The electrode assembly (313) has a pair of electrocardiography electrodes (309, 310), a pair of terminated electrical connections (311, 312) that are each coupled to one of the electrocardiography electrodes (309, 310), and a backing (20) to which the electrocardiography electrodes (309, 310) are affixed. The wearable monitoring ensemble (300) creates a more natural experience for wearers and can be used to produce an expanded dataset for diagnosis because the ensemble (300) can collect data during activities of daily living and can capture cardiovascular events outside of clinical observation, which is otherwise not practicable, especially for athletes.
摘要:
Physiological monitoring can be provided through a syncope sensor (64, 66) embedded into an electrocardiography monitor (12), which correlates syncope events and electrocardiographic data. Physiological monitoring can be provided through a lightweight wearable monitor (12) that includes two components: a flexible extended-wear electrode patch (15) and a reusable monitor recorder (14) that removably snaps into a receptacle (25) on the electrode patch (15). The wearable monitor (12) sits centrally on the patient's sternal midline (16) and includes a unique narrow "hourglass"-like shape, significantly improving the ability of the monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and QRS interval signals. The electrocardiographic electrodes (38, 39) on the electrode patch (15) are tailored for axial positioning along the midline (16) of the sternum (13) to capture action potential propagation in an orientation that corresponds to the aVF lead in a conventional 12-lead electrocardiogram, which senses positive P-waves (271).
摘要:
Physiological monitoring can be provided through a wearable monitor that includes two components, a flexible extended wear electrode patch and a removable reusable monitor recorder. The wearable monitor sits centrally (in the midline) on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline (or immediately to either side of the sternum) benefits extended wear by removing the requirement that ECG electrodes be continually placed in the same spots on the skin throughout the monitoring period. Instead, the patient can place an electrode patch anywhere within the general region of the sternum. Ensuring that the quality level of ECG recording remains constant over an extended period of time is provided through self-authentication of electrode patches. The monitor recorder implements a challenge response scheme upon being connected to an electrode patch. Failing self-authentication, the monitor recorder signals an error condition.
