    摘要: An apparatus comprises an ambulatory cardiac signal sensing circuit configured to provide an electrical cardiac signal representative of cardiac activity of a subject and processor. The processor includes a feature module, a correlation module, and an ischemia detection module. The feature module is configured to identify a fiducial feature in the cardiac signal and locate one or more cardiac features in the cardiac signal using the fiducial feature. The correlation module is configured to calculate a measure of similarity of morphology for a segment of the cardiac signal that includes the cardiac features. The ischemia detection module is configured to detect a change in the measure of similarity and determine whether the detected change in the measure of similarity is indicative of ischemia.

    摘要: A cardiac rhythm management (CRM) system includes an implantable medical device that delivers anti-tachyarrhythmia therapies including anti-tachyarrhythmia pacing (ATP) and a hemodynamic sensor that senses a hemodynamic signal. The implantable medical device includes a hemodynamic sensor-controlled closed-loop ATP system that uses the hemodynamic signal for ATP capture verification. When ATP pulses are delivered according to a selected ATP protocol to terminate a tachyarrhythmia episode, the implantable medical device performs the ATP capture verification by detecting an effective cardiac contraction from the hemodynamic signal. The ATP protocol is adjusted using an outcome of the ATP capture verification.

    摘要: Systems and methods for deploying a sensor assembly onto a cardiac lead are disclosed. The sensor assembly can include a resilient cuff having one or more sensor modules for sensing physiological parameters within the body. The resilient cuff may have a substantially cylindrical shape having an inner diameter that is smaller than an outer diameter of the lead body onto which the cuff is deployed such that the cuff is retained on the lead body by frictional forces. The sensor assembly may be deployed in conjunction with a new lead to be implanted within a chamber of the patient's heart or a body vessel, or may be deployed onto an existing, implanted lead implanted within the patient's body.
