BeneVision N1 Patient Monitor Operator’s Manual 7 - 15

■ Arrhythmias, such as atrial fibrillation or atrial flutter, which may cause an irregular baseline.

■ The patient is continuously ventricularly paced.

■ The patient has left bundle branch block.

In these cases, you may consider switching off ST monitoring.

7.7.3 Displaying ST Deviation Numerics

To display ST numerics, follow this procedure:

1. Access Tile Layout by either of the following ways:

◆ Select the Screen Setup quick key → select the Tile Layout tab.

◆ Select Main Menu quick key → from the Display column select Tile Layout.

2. Click the numeric area where you want to display the ST numerics, and then select ECG → ST.

The ST parameter display area is configured differently according to the ECG cable used:

■ When you are using the 3-lead ECG leadwires, a separate ST numeric area does not appear on the display.

The ST deviation value displays in the ECG numeric area.

■ When you are using the 5-lead ECG leadwires, the ST numeric area displays 7 ST deviation values: ST-I, ST-II,

ST-III, ST-aVR, ST-aVL, ST-aVF, ST-V.

■ When you are using the 6-lead ECG leadwires, the ST numeric area displays 8 ST deviation values: ST-I, ST-II,

ST-III, ST-aVR, ST-aVL, ST-aVF, ST-Va, ST-Vb.

■ When you are using the 12-lead ECG leadwires, the ST numeric area displays12 ST deviation values: ST-I, ST-

II, ST-III, ST-aVR, ST-aVL, ST-aVF, ST-V1, ST-V2, ST-V3, ST-V4, ST-V5, ST-V6.

This example shows the ST numeric area when 5-lead ECG cable is used. The monitor screen may look slightly

different:

7.7.4 Displaying ST Segments in the Waveform Area

You can display ST segments in the waveform area. To do so, follow this procedure:

1. Access Tile Layout by either of the following ways:

◆ Select the Screen Setup quick key → select the Tile Layout tab.

◆ Select Main Menu quick key → from the Display column select Tile Layout.

2. Select the waveform area where you want to display the ST segments, and then select ECG→ ST Segment.

(3) ST alarm off symbol (4) Lead labels

(5) ST numerics: a positive value indicates ST segment elevation, and a negative value indicates ST

segment depression.
