Brief Summary:

Hypoglycemia, frequently asymptomatic, may lead to cardiac arrythmias and induce an increased risk of cardiovascular morbidity and mortality in patients with type 2 diabetes (T2D). The study hypothesize is that the hypoglycemia reduction, achieved with the FREESTYLE LIBRE device, a Glucose Continuous Monitoring system, may decrease cardiac arrythmias associated with hypoglycemia. So the main objective is to evaluate the efficacy of the FREESTYLE LIBRE system, associated with a specific therapeutic education on the cardiac arrythmias reduction, compared to a capillary ASG system with standard therapeutic education, in patient with T2D with high risk of hypoglycemia.

This is a open, multicenter, controlled, randomized study in parallel group.

Primary Outcome Measures :
  1. Prevalence of cardiac arrythmic events during a 14 days Continuous ECG Monitoring [ Time Frame: 14 days ]

    Cardiac arrythmic events :

    • Bradycardia < 45 bpm for ≥ 10 seconds
    • or Asystole ≥ 3 seconds
    • or Atrial Fibrillation ≥ 30 seconds
    • or Non-sustained ventricular tachycardia defined as runs of beats arising from the ventricles with duration between 3 beats and 30 s with QRS ≥ 120ms and with RR intervall ≤ 600 ms (>100 bpm)


Secondary Outcome Measures :
  1. Prevalence of each component of the primary outcome [ Time Frame: 14 days ]
  2. Prevalence of ≥ 5 minutes Atrial Fibrillation episodes [ Time Frame: 14 days ]
  3. Mean QT interval [ Time Frame: First 24 hours ]
  4. Prevalence of ventricular extrasystoles [ Time Frame: First 24 hours ]
