Alarms
Table 2 displays the conditions for which an alarm may be initiated.
Selecting ECG Leads
When you select a precordial lead, a help message appears that describes the
proper location for the chest electrode. For example, if you select V1, the
message (C) 4TH INTERCOSTAL SPACE, RIGHT STERNAL BORDER is
displayed.
No message appears when you choose to display a limb or augmented lead (for
example, I, II, III, AVR, AVL, or AVF).
When you change lead selections, the new waveform is displayed and the learn
sequence is automatically initiated. If you change lead selections while processing
is suspended, the module initiates the learn sequence when you resume
processing.
