DEVICE AND METHOD FOR EVALUATION OF HEART RATE WHILE MOVING Russian patent published in 2017 - IPC A61B5/205 A61B5/245 A61B5/295 A61B5/11 

FIELD: medicine.

SUBSTANCE: inventions refer to medicine. The method for determination of human heart rate is implemented by means of a portable device, which is part of the system to determine the heart rate. The portable device for human heart rate determination contains a heart rate measuring unit for generating a of heart rate signal, a movement measuring unit for measurement of human body parts movement to generate a motion signal, and a processing unit for heart rate signal frequency quality, heart rate calculation based on the heart rate signal if the signal quality is above the predetermined threshold, and evaluation of heart rate based on the motion signal, if the signal quality is below the said threshold. The processing unit evaluates the heart rate signal based on the motion signal by estimating a constant heart rate HR_constant and determining the exponential changes in heart rate over time. The exponential change in heart rate starts from the last valid measured heart rate and ends at an estimated frequency of HR_constant, which depends on the motion signal frequency. The last reliably measured heart rate value is the last heart rate measured by the heart rate measuring unit at the time before reaching the said threshold.

EFFECT: invention provides increased accuracy of heart rate determination.
