Effect of atenolol on QT interval and dispersion in patients with syndrome X

Am J Cardiol. 1997 Sep 15;80(6):789-90. doi: 10.1016/s0002-9149(97)00519-5.

Abstract

Atenolol reduces QT dispersion and corrected QT interval in patients with syndrome X. This suggests that symptomatic improvement induced by atenolol in syndrome X patients may be partly related to reduction in abnormally augmented sympathetic tone.
