Why the study?
The study evaluated whether combining blood glucose and heart rate measurements to investigate heart rate changes related to nocturnal hypoglycemia in pediatric type 1 diabetes could improve hypoglycemia prediction.
Does continuous heart rate monitoring detect physiological changes prior to nocturnal hypoglycemia in children and adolescents with type 1 diabetes?
Comparison
HR recorded in the hour before nocturnal hypoglycemia vs sleep intervals without hypoglycemia
Design
Exploratory observational study
Follow-up
Average 194 days
Key result
Nocturnal hypoglycemia in pediatric patients with type 1 diabetes was associated with significantly higher median heart rates in the hour preceding the episode in 67% of affected subjects.

Does continuous heart rate monitoring detect physiological changes prior to nocturnal hypoglycemia in children and adolescents with type 1 diabetes?
Heart rate modifications, specifically an elevated median heart rate, occur prior to nocturnal hypoglycemia in pediatric patients with type 1 diabetes, suggesting wearable fitness trackers could aid in early detection.
Calcaterra et al. (2020) conducted an observational in Type 1 diabetes (n=17). Nocturnal hypoglycemia vs. Sleep intervals without hypoglycemia was evaluated on Heart rate changes in the hour before nocturnal hypoglycemia compared to sleep intervals without hypoglycemia. Nocturnal hypoglycemia in pediatric patients with type 1 diabetes was associated with significantly higher median heart rates in the hour preceding the episode in 67% of affected subjects.
