APPLIED PHYSICAL SCIENCES, MEDICAL SCIENCES Correction for “Synchronization of chaotic early afterdepolarizations in the genesis of cardiac arrhythmias,” by Daisuke Sato, Lai-Hua Xie, Ali A. Sovari, Diana X. Tran, Norishige Morita, Fagen Xie, Hrayr Karagueuzian, Alan Garfinkel, James N. Weiss, and Zhilin Qu, which appeared in issue 9, March 3, 2009, of Proc Natl Acad Sci USA (106:2983–2988; first published February 13, 2009; 10.1073/pnas.0809148106).
The authors note that the sentence starting on line 16 of the abstract appeared incorrectly. ‘This process creates multiple hat propagate “shifting” foci resembling polymorphic ventricular tachycardia’ should have appeared as ‘This process creates multiple premature ventricular complexes that propagate as “shifting” foci resembling polymorphic ventricular tachycardia.’
