RIBEIRO, Antonio Luiz et al. Challenges to implementation of the ECG reading center in ELSA-Brasil. Rev. Saúde Pública [online]. 2013, vol.47, suppl.2, pp.87-94. ISSN 0034-8910.  https://doi.org/10.1590/S0034-8910.2013047004406.

Electrocardiography is an established low-cost method of cardiovascular assessment, utilized for decades large epidemiological studies. Nonetheless, its use in large epidemiological studies presents challenges, especially when seeking to develop a reading center. This article describes the process, difficulties and challenges of implementing an electrocardiogram reading center in Brazilian Longitudinal Study for Adult Health (ELSA-Brasil). Among the issues discussed, we have emphasized: the criteria for selection of the electrocardiography machine and the central for storage and management of the machines; the required personnel; the procedures for acquisition and transmission of electrocardiographs to the Reading Center; coding systems, with emphasis on the Minnesota code; ethical and practical issues regarding the delivery of reports to study participants; and aspects related to quality control.
