Study Summary

The objective of this study is to compare the ULV (Upper Limit of Vulnerability)/DFT (Defibrillation Threshold) efficacy between the 2.5, 3.5 and 4.5 ms membrane time constant based biphasic defibrillation waveforms. This comparison will result in identifying the optimal membrane time constant when programming the "tuned" defibrillation waveform.

Interventions

  • DEVICE Implantable Cardioverter Defibrillator (ICD), Cardiac Resynchronization Therapy (CRT-D)
