Abstract: A method of determining signal quality in a patient monitoring device includes acquiring one or more signals using the patient monitoring device. One or more signal quality metrics are determined based on the one or more acquired signals. A noise condition is detected based on the one or more signal quality metrics, and a determination is made whether the noise condition should be classified as intermittent or persistent. One or more actions are taken based on the classification of detected noise as intermittent or persistent.

Abstract: Provided are systems and methods for blood pressure assessment using a wrist and cardiac device. In one embodiment, the wrist device receives a synchronization pulse, indicating cardiac onset, and generates blood-arrival signal data. In another embodiment, the wrist device receives cardiac signal data and generates blood-arrival signal data. The synchronization pulse or the cardiac signal data and the blood-arrival data are synchronized. The synchronization pulse or cardiac signal data and the blood-arrival signal data are processed to determine a pulse transit time between the heart and the wrist device. This pulse transit time and patient parameter are input into a trained neural network to generate an assessed blood pressure. The cardiac signal data can be generated by an electrical, acoustical, echocardiographic, or ballistocardiograph sensor. The blood-arrival signal data can be generated by an optical sensor, a tonometry sensor or a pressure-sensing sensor.

Abstract: Embodiments of the present disclosure provide systems and methods for performing ECG-based authentication. A set of electrocardiogram (ECG) signals of a user may be received by a computing device from an ECG monitor. The computing device may be associated with a resource to which the computing device controls access. An ECG profile for the user may be determined based on the set of ECG signals. In response to receiving a request to access the resource, an authentication ECG signal may be requested to authenticate the user. The authentication ECG signal may be received from the ECG monitor and compared to the ECG profile of the user to determine whether the authentication ECG signal matches the ECG profile. In response to determining that the authentication ECG signal matches the ECG profile, the user may be authenticated and granted access to the resource.

Abstract: An example method of analyzing electrocardiogram (ECG) signals includes receiving, at an ECG device, ECG signals from a multi-lead ECG system. The multi-lead ECG system includes multiple electrodes and leads, and each lead of the multi-lead ECG system provides one of the ECG signals and is coupled to more than one of the multiple electrodes, where certain electrodes are coupled to more than one lead. The method also includes detecting artifact in one or more of the ECG signals, classifying the artifact as a type of artifact, determining which leads of the multiple leads contain at least a threshold amount of the type of artifact, for the leads of the multiple leads that contain at least the threshold amount of the type of artifact identifying a common electrode to the leads, and generating a notification by the ECG device indicating that the common electrode is sensing the artifact.
