Snippet: The sample was described, for continuous variables, by mean and standard deviation or median and interquartile range (IQR), when appropriate, and for categorical variable by proportion. The concordance between the ECG methods was assessed by weighted kw-Cohen index, with its relative significance, taking as the end point variable the standard 6-lead ECG group. The Bland-Altman method with a 95% confidence level was applied for P, PR, QRS, T and Q.....
Document: The sample was described, for continuous variables, by mean and standard deviation or median and interquartile range (IQR), when appropriate, and for categorical variable by proportion. The concordance between the ECG methods was assessed by weighted kw-Cohen index, with its relative significance, taking as the end point variable the standard 6-lead ECG group. The Bland-Altman method with a 95% confidence level was applied for P, PR, QRS, T and QT interval measurements. Since differences between the two measurements did not follow a normal distribution, a nonparametric approach (median value and IQR) was used to determine the limits of agreement. P values were considered significant at the 0.05 level. Amplitude of the waves was not considered in this preliminary analysis because currently the software doesn't allow voltage variation.
