The most important task of health care in a civilized state, which contributes to the stability of the society, is ensuring the rights of a citizen on medical service regardless his or her social status and residence... However, while the problems of provisioning medical and prophylactic institutions with full-fledged financing, equipping with up-to-date equipment and other resources can be solved at least theoretically, it is impossible to staff each regional hospital with world-class specialists even in theory. Such problem can be solved only by introducing telemedical technologies into the practice of health care institutions.
(Concept of development of telemedical technologies in the Russian Federation; approved by the order of the Ministry of Health of RF No. 344/76 from August 27,2001)
Summary: «Telecard» - is a functionally complete part of medical diagnostic set «Tredex» (designed and manufactured by LLC «TREDEX Company», Kharkov), intended for transtelephone ECG consultations within the scope of telemedical approach to the creation of the system of urgent cardiological diagnosis. It has a number of undeniable advantages that distinguish it on the background of existing counterparts; ensures transmission of a digital synchronous standard 12-channel ECG over any distance by means of any voice communication channels (standard telephone lines, mobile phones, radio extenders of any model, portable and stationary radio stations, etc.)
Classical spectral evaluation is widely used at electroencephalogram analysis. A method of spectral analysis is proposed, which makes it possible at implementation of any value to increase the frequency resolution of the method and lower the level of side lobes. В Preliminary results of EEG analysis are given in the illustrations.
Last years in Ukraine are marked with the long-awaited beginning of processes of healthcare system reformation, the program and trends of which are stated in the foundational documents...
The influence of GSM phone on electroencephalogram is still at the stage of study [1-3]. Significantly, it is caused by difficulties and inability to record a clear EEG during usage of this type of telephone by the patient. Therefore for evaluation of such influence data that was received either using the unmodulated signal generator or by the researching residual effects after turning of cellular phone are used very often. The both of this approaches do not describe the real influence of modulated high frequency signal in EEG in real time and that is why they can be used only for initial estimation of such influence.
In spite the progress in telemedicine, wide use of digital technologies and other achievements of data transfer systems, transtelephonic ECG up till now cannot compete with standard one as to its quality. Therefore it is supposed that an ECG transmitted via phone cannot be a valid document describing the electric activity of the patient’s heart. This widely spread opinion was undoubtedly correct and based on serious errors of transtelephonic electrocardiography that lover its diagnostic value.
It was concluded that the spectral analysis of evoked responses by using FFT (linear system analysis) in relation to brain (highly complex nonlinear system) may mislead neuroscientists.
