Abstract

In normal children, any procedure that increases heart rate, such as the tilt test, may shorten the QT interval. The effect of the tilt test on QT interval in children with syncope remains unknown. We analyzed the response of RR and QT intervals during a tilt test in 3 groups of children: 28 healthy children (group 1), 26 with syncope of unknown etiology and negative tilt test results (group 2), and 17 with vasovagal syncope (group 3). During the tilt test, RR and QT intervals were significantly shortened in groups 1 and 2. In group 3, RR interval was lengthened during syncope whereas the QT interval remained constant. QT interval lengthening during the tilt test is not a characteristic finding in normal children or in children with vasovagal syncope.
