Abstract

The invention discloses a noninvasive blood glucose detection method and system based on electrocardiosignals. The noninvasive blood glucose detection method comprises the steps that by obtaining theelectrocardiosignals, the corresponding electrocardiosignal pRRx sequence is obtained, through linear analysis and/or nonlinear analysis of the pRRx sequence, corresponding characteristic indexes areobtained, and the calculated characteristic indexes and corresponding blood glucose values are used as input and labels for machine learning and training to obtain a model function of the corresponding relationship between the characteristic indexes of the electrocardiosignals and the blood glucose values; and when the blood glucose value at a certain time point is to be detected, by obtaining theelectrocardiosignal before the time point, calculating and according to the characteristic indexes of the electrocardiosignal, the blood glucose value at the time point can be obtained through the model function. Compared with the prior art, the electrocardiosignals acquired non-invasively are used as source signals, the cost is low, safety and efficiency are achieved, in addition, the calculation amount of the blood glucose detection process of the noninvasive blood glucose detection method is small, the algorithm complexity is low, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of non-invasive blood sugar detection, in particular to a non-invasive blood sugar detection method and system based on electrocardiographic signals. Background technique [0002] There are currently two mainstream blood sugar self-testing methods, invasive and minimally invasive. [0003] Invasive and invasive blood glucose monitoring methods require a blood glucose meter, lancets and blood glucose test strips. The main principle is to measure blood sugar by measuring the current generated by the reaction of glucose in the blood with glucose dehydrogenase or glucose oxidase in the test paper. The advantage of this method is that the measurement results are more accurate. The disadvantage is that the dehydrogenase is not unitary to glucose and is prone to false blood sugar; the oxidase is unitary to glucose, but it is easily oxidized to affect the measurement results. At the same time, this invasive detect...
