6-Lead Placement for Hexad Derived 12-lead
The Hexad ECG lead system uses a 6-lead set connected to four limb electrodes (using Mason-Likar
placement) and two chest electrodes. The algorithm derives the four remaining V-leads to provide a
non-diagnostic 12-lead view, including ECG waves and ST/QT measurements.
The two chest leads for the 6-lead placement for Hexad must be positioned at two of the V1 to V6
positions. The following combinations of positions can be used:
V1 and V3
V1 and V4
V1 and V5
V2 and V4

About ECG Leads

To make it possible to compare measured ECG signals, the electrodes (or lead sets) are placed in
standardized positions, forming so-called "leads". To obtain ECG signals optimized for use in
diagnosis and patient management in different care environments, different lead sets in varying lead
placements can be used. You can use either standard lead placements or EASI lead placements with
this monitor.
When placing electrodes, choose a flat, non-muscular site where the signal will not be interfered with
by either movement or bones. Correct lead placement is always important for accurate diagnosis.
Especially in the precordial leads, which are close to the heart, QRS morphology can be greatly altered
if an electrode is moved away from its correct location.
