Detailed Description:

Shocks delivered to patients by defibrillators, while life-saving, can create anxiety, pain and decrease quality of life. Previous studies have shown that device programming and features can safely reduce the number of shocks patients receive. This study will explore the extent to which physicians use these programming and features. It will determine whether repeat and frequent awareness to how they program their own subjects and the programming trends of all enrolled subjects will change their programming patterns. This will be accomplished by understanding physicians' device programming behaviors and providing reports as a tool to help physicians manage their subjects and provide shock reduction programming recommended by previous publications.
