FIELD: medicine; medical engineering. SUBSTANCE: analyzer has cardioelectrodes, lead switch, biopotential amplifier, filter unit, comparator, univibrator, cardiac rhythm processing unit, and indication unit. In addition, analyzer includes micropower preamplifiers positioned directly on measuring electrodes, and programmable amplifier combined with peak detector. Each of the amplifiers uses follower circuit, its input is connected directly to electrode, and its output is connected to input of biopotential amplifier through lead switch. EFFECT: enhanced reliability. 1 dwg
