3: Working with the HeartStart XL+
NOTES: In synchronized cardioversion mode, the R-Wave arrows indicate which R-Waves would trigger a shock if
the shock button is pressed.
In Demand Mode Pacing, the time until the next delivered external pace pulse is from the previous pace
pulse or the R-Wave arrow, whichever is the most recent. R-Waves immediately after the an external pace
pulse are not marked because they are likely caused by the pace pulse.
The displayed heart rate is determined by the arrhythmia analysis which is independent from R-Wave
arrows for synchronized cardioversion or for Demand Mode pacing.
Wave Sectors 2 & 3
Wave Sectors 2 and 3 are automatically populated when the parameter source's cable is connected to the
HeartStart XL+. If the parameter source is the configured choice of a particular wave sector, it is
displayed in that wave sector when available. Available waveforms include: Paddles, Pads, I, II, III, aVR,
aVL, aVF, V, Pleth and a Cascade Wave from Wave Sector 1.
You can also select an annotated ECG for Wave Sector 2. See
Changing Displayed Waveforms
Wave Sector 1 has a dedicated Lead Select button
change the displayed lead/source. Waveforms displayed in the other sectors are changed for the current
event using the Menu Select button. See
Soft Key Labels
The four soft key labels correspond to the soft key buttons located immediately below. See
These labels change, as appropriate, according to the current display view and function. Soft key labels
appearing as gray text indicate the soft key is inactive.
