간단한 개요
Twenty-one patients with insulin-treated type 2 diabetes with diabetic complications will be recruited to Part 1 of the study, a three-hour combined hyper- and hypoglycaemic clamp, along with a control group of twenty-one individuals with normal glucose tolerance matched for age, gender, and body mass index. Patients with type 2 diabetes will be scheduled for a three-week run-in period with LR and CGM prior to partic...더 보기

Patients with type 2 diabetes Insulin-treated type 2 diabetes with diabetic complications | Combined hyper- and hypoglycaemic clamp During the entire clamp, participants will be monitored by ECG, pulse oximetry, and blood pressure and plasma glucose will be measured bedside every fifth minute. Additionally, patients with type 2 diabetes will be monitored by a loop recorder (LR) and a continuous glucose monitor (CGM). Comparison of LR and CGM recordings with the recordings obtained by ECG Holter monitor and blood sampling will be used for validati...더 보기 Loop recorder (Reveal LINQ, Medtronic, Minneapolis, MN, USA) Implantation of a loop-recorder Continuous glucose monitoring (iPro2, Medtronic, Minneapolis, MN, USA) Monitoring with a continuous glucose monitor |
