6.1.3 Monitoring ECG with a 4-lead cable
ECG monitoring with a 4-lead cable allows the user to monitor Leads I, II, III, AvL, AvR and AvF. Up to two
leads can be displayed at any time. Four wire ECG monitoring requires the use of a 4-lead/electrode cable
– see “12 Accessories list of the Tempus Pro”.
The 4-lead cable should be pre-attached to the Tempus in the green connector.
Electrode Positions for 4-lead ECG Monitoring (torso or limbs)
The cable terminates in conventional 4 mm snap connections which can be used with various commonly
available disposable ECG electrodes. Two types of cables are provided for compliance with AAMI and IEC
guidelines. For details of cable part numbers, see “12 Accessories list of the Tempus Pro”.
These are labelled:
Position AAMI Label/Colour IEC Label/Colour
Right mid-clavicular line under clavicle / right wrist RA White R Red
Left mid-clavicular line under clavicle / left wrist LA Black L Yellow
Left hip / left ankle LL Red F Green
Right hip / right ankle RL Green N Black
If the ECG is inoperable then the ECG will either show a “Leads off” error for the specific Lead that is
unavailable or will show a technical error as described in section “7.4 Technical alarms”.
