ECG Module
5-8-1 Overview
The Vivid™ S5 N and Vivid™ S6 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 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.
The ECG module is located in the cabinet cage assembly (see Figure 5-6 "Cabinet Cage Assembly in
Opened Position" on page 5-8 ). All power and communication is supplied to the ECG module via the
USB hub located in the keyboard module as shown in Figure 5-39 "ECG Patient I/O Module" on page
5-50 .
A general block diagram of the ECG Patient I/O Module is shown in Figure 5-40 below.
