Figure 8: — LS scan test and LS setup on the OMNI™ II Programmer. A: LS channel signals measured with repeat sampling at 0.3–1.7 mV (blue histograms) and with respect to right ventricular (RV) channel sensing (time zero) after the “Automatic Scan” button is selected. More sensitive settings detect signals that are not specific for the near-field LS pacemaker lead and sense the single local beat multiple times. The scan suggests an LS channel sensitivity of 1.7 mV for programming. B: The display when “Go to LS setup” is chosen. The LS channel sensitivity, refractory periods, local sense alert window (LSAW), and LS-CCM delay are programmed here. The LSAW begins +6 ms after V channel sensing and extends out to +36 ms from time zero. The LSAW (yellow) and LS-CCM delay (blue) windows are shown in a linear timeline at the top of the panel.
