Figure 3. Bland-Altman plot demonstrating differences in
between 12-lead QT measurement and telemetry QT measurement;
Figure 3A. Bland-Altman Plot for differences in manually-measured
corrected QT (Bazett) on 12-lead ECG vs. 7-lead derived ECG.Figure 3B. Bland-Altman plot for differences in
manually-measured corrected QT (Bazett) on 12-lead ECG vs. Lead II
Telemetry. In both plots, the solid blue line represents no bias. Solid
red line represents mean bias between all measurements. Dashed red line
represents ± 2 standard deviations from the mean. Dashed purple line
represents ± 3 standard deviations from the mean.
