Diurnal variations of QT interval after cardiac transplantation
Abstract
The QT interval decreases with increasing heart rate (HR) induced either by exercise or atrial pacing.1,2 Autonomic innervation appears to have a direct influence on the QT interval independent of the effect on HR, as the QT interval shortens after autonomic blockade during atrial pacing.3,4 The denervated transplanted heart offers a unique model for further clarifying QT changes in the absence of autonomic innervation. In a previous study of …
