40 – US-ENGLISH
Pacing thresholds: Acute thresholds should be lower than 1 V (or 2 mA)
for a 0.35 ms pulse width, in both ventricles and in the atrium.
Sensing thresholds: For proper right ventricular sensing, the amplitude
of the R-wave should be greater than 5 mV. For proper atrial sensing, the
amplitude of the P-wave should be greater than 2 mV.
Pacing impedance measurements: Right ventricular, left ventricular
and atrial pacing impedances should range from 200 to 3000 ohms (refer
to the lead characteristics, especially if high impedance leads are used).
14.9. LEAD CONNECTION
Implant the ventricular leads, then the atrial lead.
Each lead must be connected to the corresponding connector port.
The position of each connector is indicated on the casing.
CAUTION: Tighten only the distal inserts.
To connect each lead, proceed as follows:
1. Clean the lead terminal pins thoroughly, if necessary (device
replacement).
2. Lubricate the lead terminal pins with sterile water, if necessary.
3. Do not insert a lead connector pin into the connector block without
first visually verifying that the lead port is not filled with any
obstacle.
4. Insert the screwdriver into the pre-inserted screw socket of the
appropriate port (in order to allow excess air to bleed out and to
make the insertion of the lead pin easier).
5. Insert the lead pin all the way into the port (check that the pin
protrudes beyond the distal insert).
6. Tighten, check the tightness and ensure the lead pin still
protrudes beyond the distal insert, and did not move.
