| description | The invention relates to an electronic device for amplifying and multiplexing the electrical cardiac signals, meant to be used within an ECG apparatus. According to the invention, the device comprises a transitory voltage protection block (1) and represents the input block for the electrical signals gathered from the patient's body, by means of some electrodes, an impedance adapting block (2) comprising some operational amplifiers arranged in repeater configuration, at the output of which there are gathered the electrical signals corresponding to unipolar leads, precordial leads and Wilson's central terminal, an analogous demultiplexer block (3) at the output of which there can be retrieved two electrical signals selected from the input signals, whose difference is amplified in a block (4) consisting of differential amplifiers, also playing the role of rejecting the common-mode noises, the signals obtained thereby being applied by a signal amplifying block (5) to reach an amplitude necessary to some analogous-digital convertors within a microprocessor (microP) which takes over and processes said signals. |
