RECORDING THE ECG 24
NOTE:
The gain of the ECG can be switched between 5(
}
) and 10 (
{
) mm/mV. The normal
adult setting should be 10 mm/mV, which is represented by a taller calibration symbol at the
bottom of the center ECG Display
screen. To select 5 mm/mV (e.g. for pediatrics applications)
briefly press the REV
key.

3.2 Thorax Placement Option
Place the BIOLOG 3000
i
on the patient’s left anterior chest with the
electrode feet firmly against the skin.
For ideal placement in Lead II, when viewing the BIOLOG 3000
i
from
the front:
•
The lower right electrode foot is the positive electrode (+). It
should be placed over the apex of the heart.
•
The upper left electrode foot is the negative electrode (–). It
should be placed on the sternum, as close as possible to the
manubrium.
•
The other two electrodes act as references, with at least one
reference electrode in contact with the thorax.
•
The BIOLOG 3000
i
is now ready for monitoring.
