14. IMPLANT PROCEDURE
RV to Case+SVC RV to Case RV to SVC
The polarity of shock is determined by the parameter itself.
14.9. MEASUREMENT OF THRESHOLDS AT IMPLANT
Pacing and sensing thresholds should be measured at implant.
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 appropriate right ventricular sensing, the amplitude of the R-wave should be greater
than 5 mV.
For appropriate 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).
Please refer to the leads user manuals for more details on the expected electrical
performances of the leads.
14.10. LEADS 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.
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).
