In the article by Sommer et al, “Pathophysiology of Congenital Heart Disease in the Adult: Part III: Complex Congenital Heart Disease,” which appeared in the March 11, 2008, issue of the journal (Circulation. 2008;117:1340–1350), the following correction should be made:
On page 1342, toward the top of the right column, the statement, “Resting ECGs typically have a q wave in the left precordial leads (due to anatomic reversal of the septum itself) . . .” is incorrect, and the sentence should be replaced by, “The septum (and the conduction system tissue that runs through it) is reversed, such that depolarization of the septum occurs from right to left (morphologic LV to morphologic RV). This typically produces a qS pattern in the right-sided precordial leads and the absence of Q waves in the left precordial leads.”
This change has been made to the current online version of the article. The authors regret the error would like to thank several astute readers for pointing out the mistake.
