Kurzbeschreibung
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...Mehr anzeigen

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...Mehr anzeigen 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 |

Part 1: Clinically relevant arrhythmias | Composite endpoint including atrial fibrillation, brady-arrhythmias and tachy-arrhythmias. Clinically relevant brady-arrhythmias are defined as sinus arrest for more than 3 seconds, frequency below 30 beats per minute (bpm), or high grade atrioventricular (AV) block including Mobitz Type II and third-degree AV block. Clinically relevant tachy-arrhythmias are defined as sustained ventricular tachycardia (duration \>30 seconds), and non-sustained ventricular tachycardia. | 0-240 min during the combined hyper- and hypoglycaemic clamp |
Part 2: Prevalence of clinically relevant arrhythmias as defined above | Prevalence of clinically relevant arrhythmias as defined above | Within 12 months |
Part 2: Clinically relevant arrhythmias during hypoglycaemia compared to euglycaemia | Clinically relevant arrhythmias during hypoglycaemia compared to euglycaemia | Within 12 months |
