Abnormalities of the corrected QT interval in familial dysautonomia: an indicator of autonomic dysfunction

J S Glickstein et al. J Pediatr. 1993 Jun.

Abstract

We report abnormalities in corrected QT intervals with changes in position and after exercise in patients with familial dysautonomia and confirm the previously reported finding of abnormal heart rate and blood pressure responses. Prolonged corrected QT intervals (> 440 msec) with lack of appropriate shortening with exercise is a noninvasive means of demonstrating an aberration in autonomic regulation of cardiac conduction.
