14. IMPLANT PROCEDURE
Connectors:
The quadripolar connector is compatible with the DF-4 standard (refer to the “Lead
evaluation and lead connection” sub-section in the “Warnings and precautions” section).
14.8. SHOCK CONFIGURATION (+ -> -)
The shock configuration is the energy pathway between the defibrillation electrodes. If an
atrial coil is present, the shock configuration can be programmed for bi-directional shocks.
Programming:
When active case and SVC are both programmed to Yes, the shock configuration can be
programmed to:
─ RV to Case (or Case to RV),
─ or RV to SVC (or SVC to RV),
─ or RV to Case+SVC (or Case+SVC to RV).
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 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).
14.10. LEAD CONNECTION
Implant the ventricular lead.
The lead must be connected to the corresponding connector port. The position of each
connector is indicated on the casing.
Tighten only the distal insert.
