7.7.3 Displaying ST Numerics

When [ST Analysis] is switched on, ST digital area is displayed on the screen. The loca-

tion of the ST digital area is dependent on the display configurations. For how to set the

location of the ST digital area, refer to "Configuring the Display" on page 4 - 2.

Numerics displayed in the ST digital area are different according to the lead type:

■ When the 3-lead ECG leadwires are used, the ST digital area is not displayed. A ST

value is displayed in the HR digital area.

■ When the 5-lead ECG leadwires are used, seven ST values (ST-I, ST-II, ST-III, ST-aVR,

ST-aVL, ST-aVF, ST-V) are displayed in the ST digital area.

■ When the 6-lead ECG leadwires are used, eight ST values (ST-I, ST-II, ST-III, ST-aVR,

ST-aVL, ST-aVF, ST-V

a, ST-Vb) are displayed in the ST digital area.

This example shows the ST digital area when the 6-lead ECG leadwires are used. Your

screen may look slightly different:
