- Primary Outcome Measures
Name Time Method To characterize the non-incidence of device-related complications after Cobalt XT implantation. To characterize the incidence of abnormal battery drain complications after implantation. To summarize the reasons and measures for system changes including removal of study devices. To evaluate the efficacy and safety of iATP for VT after 12 months. To assess stability 12 months after ASQ implantation. In addition, to evaluate safety information for adverse events and equipment failures through a 12-month follow-up period.
- Secondary Outcome Measures
Name Time Method The ancillary objectives are descriptive in nature and are intended to gain additional information to further assess safety and performance (with a focus on the acute and chronic timeframe) of iATP and ASQ, and the patients implanted with Cobalt XT. There are no specific sample size requirements for the following ancillary objectives. The ancillary objectives are as follows:<br>- Implant electrical summary<br>- Characterization of the implant procedure<br> - Total implant time<br> - Lead implant success rate<br> - Number of lead position changes<br> - Final leadimplant location<br> - Characterization of drug strategy prior, during, and after implant procedure <br> - Characterization of patient profile<br>- Indication<br>- Demographics<br>- Medical History<br>- QO
