[An experimental unit for high-resolution electrocardiography and the method of recording of late ventricular potentials].
One of the methods of recording late ventricular potentials, markers of decelerated depolarization of the heart ventricles, is depicted. The complex suggested by the authors consists of an interface connected to the personal computer, a block for cardiosignal processing, and an analog-to-digital converter. The averaging is realized after preliminary signal processing, which results in the computation of the mean period of the QRS. The mode of automatic amplification is provided as are alterations of the lower frequency of the section of the band-pass filters as well as the switching on of the rejection filter.
