摘要： A method includes receiving an anatomical map of at least a portion of a heart. Positions and respective electrocardiogram (ECG) signal amplitudes measured at the positions are received for at least a region of the anatomical map. The ECG signal amplitudes are interpolated to derive a surface representation of the ECG signal amplitudes over the region. The surface representation of the ECG signal amplitudes is presented overlaid on the anatomical map.

摘要： In one embodiment, a medical system includes a catheter configured to be inserted into a heart of a living subject, and including electrodes configured to capture electrical activity of the heart at respective position in the heart, a display, and processing circuitry configured to receive position signals from the catheter, and in response to the position signals compute the respective positions of the electrodes, generate an anatomical map responsively to respective ones of the computed positions, find an anatomical feature of the heart and a position of the anatomical feature responsively to the respective positions of, and electrical activity captured by, respective ones of the electrodes, automatically segment the anatomical map responsively to the found position of the anatomical feature, and render the anatomical map to the display.

摘要： A method, including configuring, in a memory, a first buffer to store first buffer data, a second buffer to store second buffer data, and a variable indicative of a persisted size of real-time data persisted to a storage device. On the storage device, a file is configured to store the real-time data and a field is configured to store the variable. A stream of the real-time data is received, and the stream is appended to the first buffer data. Upon meeting a write criteria, the first buffer data in is swapped with the second buffer data, a buffer size of the second buffer data is added to the variable, and the second buffer data is conveyed from the second buffer to a write cache. Upon meeting a commit criteria, the stream stored in the write cache is appended to the file, and the variable is persisted to the field.

摘要： In one embodiment, a medical system includes respective electrodes for application to a body of a subject and to output a set of respective activation signals in response to electrical activity of a heart of the subject captured over a sequence of heartbeat intervals, and a processor to classify a first heartbeat interval of the set of activation signals as a first morphological template, compute a measure of similarity between a second heartbeat interval of the set of activation signals and the first morphological template, group the second heartbeat interval of the set of activation signals in a first morphological group with the first morphological template responsively to the measure exceeding a predefined threshold, and classify the second heartbeat interval of the set of activation signals as a second morphological template responsively to the measure not exceeding the predefined threshold, and repeat the above, mutatis mutandis, for subsequent heartbeat intervals.

摘要： An apparatus includes a shaft, a flexible distal-end assembly, two or more sensing-electrodes, and a fiber-optic shape sensor. The shaft is configured for insertion into a body of a patient. The flexible distal-end assembly is fitted at a distal end of the shaft. The two or more sensing-electrodes are disposed over the distal-end assembly and are configured to generate signals indicative of positions of the sensing-electrodes in the body. The fiber-optic shape sensor is coupled to a portion of the distal-end assembly, wherein the two or more sensing-electrodes have α-priori known distances from a known location over the fiber-optic shape sensor, and wherein the fiber-optic shape sensor is configured to provide an indication of a spatial deformation of the flexible distal-end assembly.
