# Long QT syndrome

In the online version of this Practice article by Dominic J Abrams and colleagues, an error in figure 2 slipped through at proof stage (BMJ 2010;340:b4815, doi:10.1136/bmj.b4815). The figure’s caption correctly stated that “The QT interval is measured from the onset of the Q wave to the end of the T wave, defined as the intersection of the tangent to the steepest downslope of the T wave and the baseline” but the arrows indicating the onset and the end of the interval did not accurately reflect this. A revised figure is on bmj.com (www.bmj.com/cgi/data/bmj.b4815/DC1/1). Figure 2 in the print version of this article is correct.
