Abstract
Figure 1: Panel A: Swallow, B: TLESR with no Reflux, C: TLESR with reflux. Row 1: TZ line extracted automatically by the computer program (red line) superimposed on the HRM recording. Note the differences in amplitude and duration of the TZ signal, Row 2) Impedance contour map plot, Row 3) Symbolic representation of the normalized TZ signal indicating onset, duration, and a time window index to find lift amplitude on the impedance TZ signal.
