effect of glucose variability on QTc duration and dispersion in patients with type 2 diabetes mellitus

ABSTRACT

Objective: Glycemic variability [GV] is a new term with the episodes of hyper and hypoglycemia in diabetic patients. Both prolonged QT interval and QTd are potential risk factors for malignant ventricular arrhythmias affecting the mortality of different groups of patients including diabetes mellitus. In this study, we aimed to evaluate if the glucose variability increasing the QTc interval and QTc dispersion in type 2 diabetes mellitus
