[95% confidence interval (CI) 0.73–0.77, P < 0.001], which was inferior to N‐terminal pro‐B‐type natriuretic peptide (AUC 0.93, 95% CI 0.92–0.94, P < 0.001), but similar to that of high‐sensitivity tropon...
The range of the PQ interval was 0.07-0.18 sec, the QRS interval 0.03-0.09 sec and the QT interval 0.14-0.26 sec. The median values were 0.11, 0.05 and 0.19 sec, respectively. Positive skew distributions were found. The data were transformed to obtain values with normal distribution. The ...
