GEH measurement example of peak and area vectors, and vector magnitude (VM). a (i) VM plotted over time, and (ii) corresponding X, Y, and Z leads. b VM plotted in a three-dimensional space. Color-coded progression from QRS onset (red) to the end of T (purple) is shown. c Measurement of (i) QT integral on VM, and (ii) SAI QRST. d. Measurement of peak SVG vector magnitude, azimuth, and elevation
