FIELD: medicine. ^ SUBSTANCE: device contains analogue unit, information storage unit, interface unit, display unit and diagnostics unit. Analogue unit consists of successively switched unit of electrodes, selector of leads, differential amplifier, suppression filter and low-frequency filter. Information storage unit includes analogue-digital transformer, generator of recording and reading, counter and memory unit. Interface unit includes digital-analogue transformer, videosignal displacer, generator of tact pulses and generator of frame and line pulses. Diagnostics unit consists of comparator, support voltage source, univibrator, microcontroller and light-emitting diode matrix. Output of low-frequency filter is connected with input of analogue-digital transformer and first input of generator of recording and reading, whose output via counter is connected with first input of memory unit. Second input of memory unit is connected to output of analogue-digital transformer, and counter output is connected with second input of generator of recording and reading. Output of memory unit via digital-analogue transformer is connected to first input of videosignal displacer, whose output is connected with display unit. Tact pulse generator via generator of frame and line pulses is connected with second input of videosignal displacer. Low-frequency filter output is connected to first input of comparator, whose second input is connected with support voltage source. Comparator output is connected with successively connected univibrator, microcontroller and light-emitting diode matrix. ^ EFFECT: application of device will allow to display person's electrocardiogram visually and perform analysis of its R-complex, determining main types of arrhythmia. ^ 2 dwg |
