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.
