6 ECG, Arrhythmia, ST and QT Monitoring
114
Standard 6-Lead Placement
Use the positions from the 5-lead diagram above but with two chest leads. The two chest leads, Va and
Vb, can be positioned at any two of the V1 to V9 or V3R to V6R positions shown in the chest
electrode diagram below (see “Chest Electrode Placement” on page 115).
The Va and Vb lead positions chosen must be selected in the
Setup ECG Menu.
Hexad 6-Lead Placement
Use the positions from the 5-lead diagram above but with two chest leads. For Hexad derived 12-lead,
the two chest leads, Va and Vb, must be positioned at two of the V1 to V6 positions shown in the
chest electrode diagram below (see “Chest Electrode Placement” on page 115). The following
combinations of positions can be used:
The Va and Vb lead positions chosen must be selected in the
Setup ECG Menu.
When Hexad lead placement is selected,
Hexad is shown beside the 1 mV calibration bar on the ECG
wave and all derived leads are marked with a "d" in front of the lead label, for example dV1.
WARNING
Hexad derived 12-lead ECGs and their measurements are approximations to conventional 12-lead
ECGs. They should not be used for diagnostic interpretations.
