Supplementary Table 2 ECG event classification after Prineas, Ronald J., Richard S. Crow, and Zhu-Ming Zhang. The Minnesota Code Manual of Electrocardiographic Findings: Including Measurement and Comparison with the Novacode: Standards and Procedures for ECG Measurement in Epidemiologic and Clinical Trails. 2nd ed., New and Enlarged. London: Springer, 2010. The classification with the indices in the table will be done only in case of abnormal/pathological results.
