Abstract
Background. Due to the large territorial extent of our country, the task of compression and transmission of medical information of various natures occupies one of the key places in providing the population with high-quality medical care. It should be noted that lossless data compression algorithms should be executed not only on common desktop computer architectures, but also on various specialized platforms used, for example, in portable medical biopotential recorders. Therefore, the task of developing and researching methods for undistorted compression of medical data is an urgent scientific and applied task, due to the development and improvement of computing technology. The aim of this work is to evaluate the methods of compression of transmitted data in biotelemetric systems using the example of compression of an electrocardiogram. To achieve this goal, it is necessary to solve the following tasks: analysis of existing methods of compression of transmitted data in biotelemetric systems using the example of compression of an electrocardiogram; selection of a method of compression of transmitted data in biotelemetric systems using the exampleof compression of an electrocardiogram. For a biotelemetric system as a radio engineering and information-measuring system, the main indicators are measurement error and reliability of data transmission. Materials and methods. The article presents a structural diagram of a biotelemetric system, based on the structure of the developed distributed cardiodiagnostic system and its communication channel, and discusses data compression methods based on redundancy reduction and wavelet transformation. Results. The analysis of the possibilities of compression methods and the calculation of the compression ratio were carried out. Conclusions. As a result of the conducted study, it was established that the wavelet transform of data is more preferable compared to the SCP-ECG standard for transmitting electrocardiographic examination data in biotelemetric systems.
