HEART FUNCTION DETERMINATION METHOD, SYSTEM AND ELECTRONIC DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2021 - IPC A61B5/24 A61B5/1455 

FIELD: medicine.

SUBSTANCE: inventions group relates to medicine, namely to a method and a system for heart function determination. When executing the method, two streams of laser radiation are formed. Each stream includes radiation from two sources with different wavelengths and different polarizations. Irradiate with streams of tissue from two different parts of the human body. These radiation streams reflected from tissues are converted into electrical signals carrying information about the heart function. Synchronization of mentioned electrical signals is provided. On the basis of these signals, heart electrical forces are determined. The system contains the first and second devices to measure the heart function parameters. Devices are designed to be installed on various parts of the human body. Each device contains a casing. A power source, two sources of laser radiation with different wavelengths and different polarizations, a memory unit for recording information about the heart function, a unit for transmitting information about the heart function parameters are installed into the casing. Each laser source is equipped with a tool to convert laser radiation into electrical signals that carry information about the heart function parameters. In this case, the system provides synchronization of the received electrical signals.

EFFECT: due to the use of laser sources with different wavelengths and different polarizations, an increase in the accuracy of determining the FF waves, segments and intervals reconstructed from electrical signals that carry information about the heart function parameters of the person, obtained from the converted radiation streams, is achieved for a long time in the course of his normal life, simultaneous recording of the cardiographic response from tissues with different sensitivity to the length or polarization of laser radiation.
