ELECTROCARDIOGRAPH FOR NON-INVASIVE REAL-TIME MICROPOTENTIAL RECORDING ON ELECTROCARDIOGRAM Russian patent published in 2015 - IPC A61B5/402 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to devices for measuring bioelectric potentials of the heart. An electrocardiograph comprises a supply unit, electrodes, a microcontroller, a computer, an analogue-to-digital converter, and a digital-to-analogue converter. The electrocardiograph has a multi-channel structure and comprises several identical channels. The electrodes are medical nanoelectrodes for the chest EEG recording. Outputs of the nanoelectrodes are connected to inputs of measuring amplifiers; outputs of the measuring amplifiers are connected to the first inputs of operational amplifiers outputs of which are connected to inputs of the analogue-to-digital converter; outputs of the analogue-to-digital converter are connected to inputs of microcontrollers, outputs of which are connected to the computer and to the second inputs of the operational amplifiers through the digital-to-analogue converter.

EFFECT: invention aims at the higher resolution of electrocardiographic equipment for non-invasive real-time micropotential recording on the electrocardiogram without applying any analogue and program filters, collecting cardiac pulses which lead to the distortion of true bioelectric activity of the heart for the purpose of early diagnostic of the heart diseases and eliminating the episodes of sudden cardiac death.
