FIELD: medical technology.
SUBSTANCE: group of inventions relates to medical technology, namely, a method for reusing data in a system for processing and displaying electrical activity of the heart, a device for processing and displaying electrical activity of the heart and a system for processing electrical activity of the heart. The device contains a memory and a processing device. The memory is made with the ability to store electrical signal data. With the help of a processing device, electrical signal data is received. In the implementation of the method, electrical signals are obtained over time using electrodes. Each signal is received through one of the electrodes and indicates electrical activity at the location of a part of the patient’s anatomical structure in three-dimensional space. The electrical signal data corresponds to electrical signals. The electrical signal data is filtered according to the first settings of the filter parameters. Information about the first mapping to display a map of a part of the patient’s anatomical structure and filtered electrical signal data is generated. An indication of the area of a part of the anatomical structure of the patient on the map is obtained. Re-filtering of the filtered electrical signal data is performed in accordance with the changed second filter parameter setting. At the same time, the stored electrical signal data that is missing in the identified area of the heart on the map is restored from memory. The received data for display in the specified area is reused. Indication of the change in the second setting of the filter parameters is received. Information about the second mapping to display the re-filtered electrical signal data in the area indicated on the map is generated. The system contains electrodes, a display device, and a processing device. The display device is designed to display a map of a part of the patient’s anatomical structure and electrical signal data.
EFFECT: thanks to the recovery from memory of the stored electrical signal data missing in the already identified area of the heart on the map, their re-filtering and display in the specified area, a more accurate and detailed map of the patient’s anatomical structure, such as the heart, is provided with the display of the re-filtered missing data on it.
