Correlations between glucose and ECG parameters and differences in ECG parameters between above- and below-mean glucose concentration (99.6 mg/dL) subgroups. Among the 210 samples from 14 subjects over five days, there were no remarkable correlations between R-, T-wave amplitudes and TWI, and glucose. There was a weak positive correlation between R/T ratio and BGL (r = .241 (P < .001). Mean T-wave amplitudes and T-wave were not different between below- and above-mean glucose subgroups. However, mean R-wave amplitude (1.91 ± 0.80 vs 1.65 ± 0.67 mV, P = .021) and R/T ratio (3.4 ± 1.4 vs 2.7 ± 0.9, P < .001) were significantly higher in the above-mean group than the below-mean group. Abbreviations: ECG, electrocardiogram; BGL, blood glucose levels; R/T, ratio between R- and T-wave amplitudes; TWI: T-wave integral.
