Diabetes Obes Metab: Rapidly rising blood sugar in adults with type 1 diabetes can reduce heart rate variability

A recent study published in Diabetes Obesity and Metabolism, an authoritative journal in the field of metabolic endocrine diseases, looked at differences in heart rate variability (HRV) during oral glucose tolerance tests (OGTT) for different blood sugar concentrations in people with type 1 diabetes.
The single-center, forward-looking, secondary outcome analysis was conducted in 17 patients with type 1 diabetes (HbA1c 7.0±0.6%) who received OGTT twice (after 12 to 36 hours of fasting) to investigate differences in HRV after rapid blood sugar fluctuations and different blood sugar range reactions during OGTT.
according to the change of glucose, the heart rate (p-lt;0.001), the mean square root value (RMSSD) (p-0.002) and QTc (p-0.04) of the difference between the entire adjacent NN periods have changed significantly, especially during the rapid rise of blood sugar HRV.
blood sugar fluctuations during OGTT had no effect on HRV .
result, HRV in people with type 1 diabetes did not change significantly in different blood sugar ranges.
HRV depends on the rate of change in glucose, especially the rapid rise in blood sugar.
