QT Interval Abnormalities in Sulfonylurea Treated Type 2 Diabetes: Relationship to Treatment Induced Hypoglycaemia

"(i) Continuous Glucose Monitoring A sterile disposable glucose-sensing sensor will be inserted into the subcutaneous tissues in either the abdomen or the upper outer quadrant of the patient's buttock. This sensor automatically measures the change in glucose in interstitial fluid every 5 minutes. The monitor will be worn for two days.~(ii)Holter Monitoring The Holter monitor to capture cardiac conduction, specifically QT interval, will be worn for the same period as the continuous glucoe monitor with study participants encouraged to perform regular daily activities."
