The following procedure is recommended for determining the length of the optional
blanking interval:
1. Place the patient on the system.
2. After establishing a stable waveform, store the paced rhythm in the view
screen.
3. Inspect the flag and measure the interval from the flag to the physiologic
response (P wave or QRS), as shown in fig. 44 and fig. 45. Residual artifacts
of the pacer may appear between the flag and the start of the QRS. You can
use the electronic calipers to measure the interval.
