6.1 Overview
The Generator starts in the ECG Synchronous mode (default
setting). When working in this mode, the Generator has to be
connected to an external R-wave detector.
6.2 External R-Wave Detector
The external R-wave detector must have the following
specifications:
•
Be FDA approved or CE marked medical grade
device.
•
Generate an output signal that is TTL/CMOS
compatible signal with an output that is a 5 V
positive logic pulse starting when the R-wave is
detected and with a length of at least 1 ms.
• Deliver an output at least 15 mA.
• The connection cable should be an RGU 174/U
cable with a length up to 90 cm.
• Since the Generator will deliver a pulse after 50 ms
from the R-wave trigger signal, it is required that
the delay between the R-wave and the trigger
signal output is less than 10 ms.
• The R-wave detector should reject erratic pulses
and ECG artifacts to assure that the triggering
signal always corresponds to an R-wave.
• It is recommended that the Generator’s outputs be
protected against defibrillator discharge.
• The
External Sync Connector
is a female BNC
connector located on the Generator’s back panel
labeled "ECG Synch. Input"
