摘要： In one embodiment, a method for monitoring a heartbeat includes receiving a heartbeat signal, the heartbeat signal including heartbeat cycles. The method also includes determining a region of interest (ROI) of the heartbeat cycles based on an identifying feature of each heartbeat cycle of the heartbeat cycles. The ROI includes a first portion of a period of a first heartbeat cycle. The method also includes sampling the first portion of the heartbeat cycle within the ROI at a first sampling rate and sampling a second portion of the heartbeat cycle outside of the ROI at a second sampling rate less than the first sample rate.

摘要： In a method of video monitoring of a subject, for example a driver of a vehicle, the video image is motion compensated by image registration techniques so that the subject's position in each frame of the video image is stable. A region of interest is defined on the skin of the subject and used to obtain a PPG signal. To compensate for variations in illumination of the subject caused by the subject's movement in the vehicle, the parameters of the calculated motion transformation used in the image registration are used to form an illumination model representing how the illumination of the subject would have changed because of the subject's motion. The illumination model is a linear or quadratic function fitted to the image intensity in the region of interest. Residuals between the fitted model and the image intensity form an illumination-compensated signal in which the photoplethysmographic signal is more clearly present. The illumination-compensated signal is analysed to obtain a PPG signal and from this estimates of one or more vital signs such as heart rate or breathing rate are obtained.

摘要： The present invention relates to a device, system and method for sensor position guidance to guide a user or the subject to place a wearable sensor to the optimum position at the subject's body. The device comprises an image data input (40) for obtaining image data of at least a subject's body area showing motion of said body area, an analyzer (41) for analyzing the obtained image data to determine one or more locations of the body area showing maximal movement caused by respiration and/or heart beat, and a guidance output (42) for selecting from the determined one or more locations an optimum location based on the strength of movement and for providing guidance information indicating the optimum location, at which a wearable sensor (6) for monitoring respiration and/or heart rate should be placed to said subject's body.

摘要： Cardiac catheterization is facilitated by generating first and second electroanatomic maps of a heart of a subject and designating common spatial locations that correspond to first electrical events on the first electroanatomic map and second electrical events on the second electroanatomic map. The common spatial locations of the first electroanatomic map and the second electroanatomic map are aligned to establish an aligned map, and using the location data on the aligned map to guide a probe to a point of interest.

摘要： An electrophysiology map, for example a map of arrhythmic substrate, can be generated by acquiring both geometry information and electrophysiology information pertaining to an anatomical region, and associating the acquired geometry and electrophysiology information as a plurality of electrophysiology data points. A user can select two (or more) electrophysiological characteristics for display, and can further elect to apply various filters to the selected electrophysiological characteristics. The user can also define various relationships (e.g., Boolean ANDs, ORs, and the like) between the selected and/or filtered characteristics. The user-selected filtering criteria can be applied to the electrophysiology data points to output various subsets thereof. These subsets can then be graphically rendered using various combinations of colorscale, monochrome scale, and iconography, for example as a three-dimensional cardiac electrophysiology model.
