Sustained QTc Prolongation During Recovery from Hypoglycemia in People with Type 1 Diabetes, Independently of Recovery to Hyper- or Euglycemia.

In people with type 1 diabetes, insulin-induced hypoglycemia prolongs cardiac repolarization, which is sustained during a 60-minute recovery period independently of recovery to hyperglycemia or euglycemia. Thus, vulnerability to serious cardiac arrhythmias and sudden cardiac death may extend beyond a hypoglycemic event, regardless of hyperglycemic or euglycemic recovery.
