Monitoring of 24-h ECG and glucose level for detection of relations between glycemia and QT interval duration in type 1 diabetics

Abstract

Aim. To study correlations between glycemia and duration of ventricular repolarization in children and adolescents with type 1 diabetes mellitus (DM). Material and methods. Parallel monitoring of ECG and glycemia was conducted in 43 type 1 MD patients (age 7-17 years, 12.8 ± 2.7) and 37 healthy children and adolescents. Results. Glycemia under 3 mmol/l and over 19 mmol/l is associated with significantly longer QTc interval compare to other blood glucose levels (437 ms and 447 ms versus 430 ms, p < 0.01). Also, in these glycemia values QTc interval duration over 440 ms (46 and 62% versus 33%; p
