Overview
The Vivid i n/ Vivid q N ECG Patient I/O module is designed to enable acquisition of the following
signals: ECG and external ECG. The different pins on the ECG input connector are specifically
assigned to support either External ECG or Internal ECG:
•
•
The ECG module is located under the keyboard assembly (see
communication is supplied to the ECG module via the USB hub located in the keyboard module as
shown in

EVISION
The Internal ECG module supports acquisition of two bipolar ECG channels: leads I, II.
The External ECG module supports acquisition of a single bipolar ECG input channel ranging
from -1 to +1 volt allowing amplification of 1000. The minimal allowed impedance is 10 M ohm.
