Outcome
- Type
- PRIMARY
- Title
- All-Cause Shock
- Description
The incidence of all-cause shocks in subjects programmed with shocks only will be compared with subjects programmed to standard therapy (ATP and shock) to assess equivalency. All shocks delivered by the device were adjudicated by an external committee as to whether they were appropriately or inappropriately delivered. All shocks, appropriate and inappropriate, contributed to the evaluation of this endpoint.
- Time frame
- 5 years
- Population
