Background: Cardiac involvement in scleroderma is a poor prognostic sign and is usually underdiagnosed, particularly in asymptomatic patient. This paper focuses on QT dynamicity and heart rate variability (HRV) in patients with scleroderma and controls in an attempt to investigate the cardiac autonomic system and ventricular repolorization.
