Early Detection of noctUrnal hypoglyCemiA in TypE 2 Diabetes Using Pulse Rate Variability Measured by a Smartwatch(EDUCATED-Smartwatch)

In patients with type 2 diabetes, it is necessary to identify and manage nocturnal hypoglycemia as early as possible, so as to reduce the damage caused by nocturnal hypoglycemia.We explore whether smartwatches can provide early warning of nocturnal hypoglycemic events in patients with type 2 diabetes by detecting changes in pulse variability.
