Figure 32.3From: Body Surface Potential MappingThe first four components resulting from singular value decomposition of the matrix of instantaneous repolarization potentials versus time in a normal recording. Each component is represented by the body-surface potential distribution (right) (distance between isopotential lines is arbitrary) and the variation of its amplitude in time (left) (time on x-axis and relative amplitude on y-axis). The first component is at the top, the fourth at the bottom.Back to chapter page
