摘要：
The invention relates to the field of medicine and is directed at increasing the precision and reliability of measurements and the accuracy of information obtained regarding heart activity, and at a simplified design. The technical result is achieved in a device for producing a cardiogram, said device containing, installed on a housing, capacitive electric field sensors, a potentiometer connected to same, a first cascade of a differential amplifier having a common mode interference filter, which receives a signal from the capacitive electric field sensors and which is connected to a second cascade of a differential amplifier having a common mode interference filter and a analog to digital converter driver, which transmits signals in parallel to first and second inputs of a two-channel analog to digital converter (ADC) having a common mode interference filter, a trigger for controlling the reception of data from the ADC to a controller which is connected to a DC power supply having interference suppression filters, a cryptoprocessor, a USB port logical switching unit, and a USB port splitter which is connected to the DC power supply and to a USB port overvoltage protection unit, and which receives signals from a power supply monitor which is connected to the USB port logical switching unit.
