Key result
An ECG-based DBSCAN-CNN approach classified low, moderate, and high blood glucose ranges with 87.94%, 69.36%, and 86.39% accuracy, and screened for diabetes with 98.48% sensitivity.
Why the study?
Monitoring different blood glucose ranges is significant for diabetes care, and changes in blood glucose stimulate the autonomic nervous system leading to electrocardiogram variations.
Does an ECG-based DBSCAN-CNN approach accurately classify blood glucose ranges in adults?

An ECG-based machine learning approach (DBSCAN-CNN) shows potential for non-invasive monitoring of blood glucose ranges and screening for prediabetes/diabetes.
May support non-invasive ECG glucose classification; hypothesis-generating and requires prospective validation before clinical adoption.
Autonomic nervous system (ANS) can maintain homeostasis through the coordination of different organs including heart. The change of blood glucose (BG) level can stimulate the ANS, which will lead to the variation of Electrocardiogram (ECG). Considering that the monitoring of different BG ranges is significant for diabetes care, in this paper, an ECG-based technique was proposed to achieve non-invasive monitoring with three BG ranges: low glucose level, moderate glucose level, and high glucose level. For this purpose, multiple experiments that included fasting tests and oral glucose tolerance tests were conducted, and the ECG signals from 21 adults were recorded continuously. Furthermore, an approach of fusing density-based spatial clustering of applications with noise and convolution neural networks (DBSCAN-CNN) was presented for ECG preprocessing of outliers and classification of BG ranges based ECG. Also, ECG's important information, which was related to different BG ranges, was graphically visualized. The result showed that the percentages of accurate classification were 87.94% in low glucose level, 69.36% in moderate glucose level, and 86.39% in high glucose level. Moreover, the visualization results revealed that the highlights of ECG for the different BG ranges were different. In addition, the sensitivity of prediabetes/diabetes screening based on ECG was up to 98.48%, and the specificity was 76.75%. Therefore, we conclude that the proposed approach for BG range monitoring and prediabetes/diabetes screening has potentials in practical applications.
