Abstract: A roller winding mechanism having a winding shaft which is created as a tube attached at one end to a drive which is coupled to the frame and at its other end mounted on a bearing on a pivot fixed to the frame.

Abstract: A roller winding mechanism comprising a winding shaft (2) which is created as a tube attached at one end to a drive which is coupled to the frame (7) and at its other end mounted on a bearing on a pivot fixed to the frame (7), whereas it comprises a shaft reinforcement (6) which is inserted into a roller winding shaft (2) and anchored firmly to a frame (7) on the side opposite to a drive (8), the bending direction of the shaft reinforcement (6) being opposite to the expected deflection of the winding shaft (2) and the initial curvature of this reinforcement (6) is such that its deformation along its length is such that its axis at maximum deformation coincides with the axis of the originally non-deformed winding shaft (2) and the reinforcement (6) is provided with rolling support bearings (10) mutually spaced apart along its length.

Abstract: A method of measuring and analyzing the ultra high frequency EKG is performed by measuring the EKG within the frequency range above 250 Hz with a dynamic range of at least 100 dB. In the UHF EKG signal positions of Rm of R wave in QRS complex of EKG are detected on the time axis and the EKG signal is converted to amplitude or power envelopes, the amplitude or power envelopes frequency range is anywhere within the limits from 0.2 Hz to at least 500 Hz. From these envelopes the amplitude and time numerical parameters that describe the myocardium depolarization inhomogeneity and electric myocardium dyssynchrony are determined, and these parameters are used for selecting the patients for multi-chamber stimulators implementation and optimization of their setting.
