Corrigendum to ‘Sensitivity of epicardial electrical markers to acute ischemia detection’ [J Electrocardiol 47/6 (2014) 836–841] ( (****) ** (***–***), (S0022073614003264), (10.1016/j.jelectrocard.2014.08.014))

Following publication of the original article (Journal of Electrocardiology. 2014 Nov.–Dec.; 47(6):836–41) we became aware of the following errors we wish to correct. These corrections have no impact over the study results, their interpretation or conclusions. Due to a careless error in computer processing script, the area under the ROC curve was incorrectly computed and reported for the demand and supply ischemia episodes as follows: for the 22 supply ischemia episodes, under the conditions of mild perfusion deficit, the area under the ROC curve was 0.93 ± 0.12 for the T-wave, 0.77 ± 0.09 for the ST40% and 0.63 ± 0.14 for the R-wave. Moreover, for the 22 demand ischemia episodes, the area under the ROC was 0.89 ± 0.17 for the T-wave, 0.73 ± 0.21 for the ST40% and 0.59 ± 0.15 for the R-wave. We have corrected that error and report revised area under the curve values as follows: to summarize all the 22 supply ischemia episodes, under the conditions of mild perfusion deficit, the area under the ROC curve was 0.83 ± 0.03 for the T-wave, 0.60 ± 0.07 for the ST40%, and 0.55 ± 0.01 for the R-wave, respectively. For all the 22 demand ischemia episodes, under the conditions of moderately elevated heart rates, the area under the ROC curve was 0.85 ± 0.02 for the T-wave, 0.56 ± 0.04 for the ST40%, and 0.33 ± 0.03 for the R-wave, respectively.[Figure presented] We regret this error in our original publication and we apologize for any inconvenience caused.
