    摘要： The present invention provides for the detection and display of polarization scrambling tissue without resolving the polarization state of the backscattered imaging beam. In one embodiment, we illuminate the tissue using two different polarizations. A first polarization determines a first image of high intensity while the second polarization determines a second image of low intensity. Comparison and combination of the first and second images determines tissue which scrambles the polarization in neighbouring detection cells.

    摘要： Systems and methods involve determination of CRT parameters using a number of CRT optimization processes. Each CRT optimization process attempts to return recommended parameters. The CRT parameters are determined based on the recommended parameters returned by one or more of the CRT optimization processes. The CRT optimization processes may be sequentially implemented and the CRT parameters may be determined based on the recommended parameters returned by a first CRT optimization process to return recommended parameters. The CRT parameters may be determined based on a combination of the recommended parameters returned. The CRT optimization processes implemented may be selected from available CRT optimization processes based on patient conditions.

    摘要： Cardiac devices and methods discriminate non-captured intrinsic beats during evoked response detection and classification by comparing the features of a post-pace cardiac signal with expected features associated with a non-captured response with intrinsic activation. Detection of a non-captured response with intrinsic activation may be based on the peak amplitude and timing of the cardiac signal. The methods may be used to discriminate between a fusion or capture beat and a non-captured intrinsic beat. Discriminating between possible cardiac responses to the pacing pulse may be useful, for example, during automatic capture verification and/or a capture threshold test.

    摘要： The present invention discloses a method for generating elevation maps or images of a tissue layer/boundary with respect to a fitted reference surface, comprising the steps of finding and segmenting a desired tissue layer/boundary; fitting a smooth reference surface to the segmented tissue layer/boundary; calculating elevations of the same or other tissue layer/boundary relative to the fitted reference surface; and generating maps of elevation relative to the fitted surface. The elevation can be displayed in various ways including three-dimensional surface renderings, topographical contour maps, contour maps, en-face color maps, and en-face grayscale maps. The elevation can also be combined and simultaneously displayed with another tissue layer/boundary dependent set of image data to provide additional information for diagnostics.

    摘要： Multi-chamber pacing may result in capture of one chamber, capture of multiple chambers, fusion, or non-capture. Approaches for detecting various capture conditions during multi-chamber pacing are described. Pacing pulses are delivered to left and right heart chambers during a cardiac cycle. A cardiac electrogram signal is sensed following the delivery of the pacing pulses. Left chamber capture only, right chamber capture only, and bi-chamber capture may be distinguished based on characteristics of the cardiac electrogram signal. Multi-chamber capture detection may be implemented using detection windows having dimensions of time and amplitude. The detection windows are associated with expected features, such as expected signal peaks, under a particular capture condition. The cardiac electrogram signal features are compared to detection windows to determine the capture condition.
