Heartbeat Coincidence: Using the Heartbeat Coincidence Feature
Strip Chart Annotation
When heartbeat coincidence detection is enabled, the annotation
HBC
prints in the
center margin of the strip chart paper following the active FHR modes. (Refer to
“Simulated Heartbeat Coincidence Detection Trace,” on page 13-5.)
As soon as heartbeat coincidence is detected, two overlaid hearts print in the
upper portion of the top grid of the strip chart paper; the hearts print every 4.5 cm for
as long a coincidence is detected. Once coincidence is resolved, two side-by-side
hearts print
once.
If you disconnect a transducer while coincidence is detected, the overlaid hearts
stop printing. In addition, the mode status line prints on the strip chart paper—
without the
HBC
annotation—indicating the deactivated mode.
