Selecting Options for Lead Display
One operational mode is available with the 91343 and 91347 multi-lead
transmitters. When all electrodes are connected to the patient, leads I, II, III, AVR,
AVL, AVF, and Vx, where x = 1 to 6, are available. When no chest lead is applied,
leads I, II, III, AVR, AVL, and AVF are available using the remaining connected
electrodes.

• Combinations of leads not included above produce invalid lead
vectors. In general, for at least one valid vector, either RL or C
and two limb leads must be connected.
• The RA lead wire must be connected to the transmitter at all
times. This lead wire also serves as the transmitter’s antenna.
• If automatic lead select is enabled in the telemetry receiver, the
loss of a lead wire connection on the patient shall result in the
remaining lead vectors in the above table to be available for
display. If the lead wire that was disconnected is restored, the
two existing lead vectors will remain displayed and will only
change by operator intervention.
