14.8. MEASUREMENT OF THRESHOLDS AT
IMPLANT
Pacing and sensing thresholds should be measured at implant.
Pacing threshold: Acute thresholds should be lower than 1 V (or
2 mA) for a 0.35 ms pulse width.
Sensing threshold: For proper ventricular sensing, the amplitude of
the R-wave should be greater than 5 mV.
Pacing impedance measurement: Ventricular pacing impedance
should range from 200 to 3000 ohms (refer to the lead
characteristics, especially if high impedance lead is used).
14.9. LEAD CONNECTION
The lead must be connected to the corresponding connector port.
The position of each connector is indicated on the casing.
CAUTION: Tighten only the distal insert.
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.
