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).
The polarity of shock is determined by the parameter itself.
14.8. 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 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.
