ABSTRACT
Late potentials (high-frequency oscillation of the initial part of ST-segment) reflect decelerated ventricular depolarization and predispose onset of reentry arrhythmias. Investigators are keenly interested in their possible exact registration. The article describes the experience of realization of late potentials registration method based on the method of Simson et al, with the use of a USSR-produced electronic apparatus. The first experience of clinical application of the late potentials registration method in patients with IHD is analysed. Presence of late potentials is correlated with spontaneous ventricular arrhythmias and possible disturbances of left ventricular contractility. The obtained data as well as analysis of technical possibilities of the developed system allow evaluation of the proposed technique as acceptable for late potentials registration.
