Response To Letter To The Editor Regarding Article "Repolarization Parameters Are Associated With Mortality In Chagas Disease Patients In The United States"

While the primary focus of the manuscript was repolarization abnormalities we regretfully did not cite the authors important work on ECG fragmentation. Unfortunately, the authors' abstract [1,2] was not noted in our initial literature search. The authors subsequently reported their data in manuscript form [3] in January of 2014. This should serve as a reminder to consider a repeat literature review after an initial manuscript is submitted, as failing to do so can lead to an incomplete review when new data becomes available in the interim.
