摘要： Techniques for detection and treatment of myocardial ischemia are described that monitor both the electrical and dynamic mechanical activity of the heart to detect and verify the occurrence of myocardial ischemia in a more reliable manner. The occurrence of myocardial ischemia can be detected by monitoring changes in an electrical signal such as an ECG or EGM, and changes in dynamic mechanical activity of the heart that are sensed by an accelerometer sensor. The heart acceleration signal can be obtained from an single- or multiple-axis accelerometer and/or a pressure sensor deployed within or near the heart. The techniques correlate contractility changes detected by an accelerometer or pressure sensor with changes in the ST electrogram segment detected by the electrodes to increase the reliability of ischemia detection.

The occurrence of myocardial ischemia can be detected by monitoring changes in an electrical signal such as an ECG or EGM, and changes in dynamic mechanical activity of the heart. Dynamic mechanical activity can be represented, for example, by a heart acceleration signal or pressure signal. The electrical signal can be obtained from a set of implanted or external electrodes. The heart acceleration signal can be obtained from an accelerometer or pressure sensor deployed within or near the heart.

摘要： An implantable device and associated method for delivering a multi-site pacing therapy includes electrodes for sensing cardiac signals and delivering cardiac pacing pulses to a first pacing site along a heart chamber and a therapy delivery module for delivering cardiac pacing pulses to a patient's heart via the electrodes. A sensing module measures an activation time at multiple pacing electrode sites along the heart chamber in response to delivering pacing pulses at the first pacing site.

摘要： Techniques for evaluating cardiac electrical dyssynchrony are described. In some examples, an activation time is determined for each of a plurality of torso-surface potential signals. The dispersion or sequence of these activation times may be analyzed or presented to provide variety of indications of the electrical dyssynchrony of the heart of the patient. In some examples, the locations of the electrodes of the set of electrodes, and thus the locations at which the torso-surface potential signals were sensed, may be projected on the surface of a model torso that includes a model heart. The inverse problem of electrocardiography may be solved to determine electrical activation times for regions of the model heart based on the torso-surface potential signals sensed from the patient.

摘要： An implantable medical device acquires a first cardiac signal in a first heart chamber and a second cardiac signal in a second heart chamber. The device determines if the first signal is unreliable. In response to determining the first signal to be unreliable, the device switches from a first cardiac arrhythmia detection mode of operation to a second cardiac arrhythmia detection mode of operation, the first detection mode requiring the use of both the first cardiac signal and the second cardiac signal and the second detection mode requiring the use of the second cardiac signal and not requiring the use of the first cardiac signal.

摘要： An implantable device and associated method for delivering a multi-site pacing therapy includes electrodes for sensing cardiac signals and delivering cardiac pacing pulses. Electrodes positioned at first and second selected pacing sites are used to deliver pacing pulses to a first heart chamber using a bipole comprising the first electrode and the second electrode. A controller is configured to determine if anodal and cathodal capture can be achieved during pacing using the bipole. Responsive to anodal and cathodal capture being achieved, the controller selects a multi-site pacing configuration comprising the bipole for singly pacing the first and second pacing sites.
