QT Interval Variability in Type 2 Diabetic Patients with Cardiac Sympathetic Dysinnervation Assessed by 123I‐Metaiodobenzylguanidine Scintigraphy

QT Variability and Sympathetic Dysinnervation. Introduction: The mechanism of adverse prognosis attributable to proarrhythmic cardiac sympathetic dysinnervation in patients with type 2 diabetes is incompletely understood. This study sought the association of cardiac sympathetic dysinnervation with temporal instability of ventricular repolarization assessed by beat‐to‐beat QT interval variability.
