Further study details as provided by St. Jude Medical:

Primary Outcome Measures:
  • Slow Ventricular Tachycardia Episodes Devices Detected (Between 120-150 Bpm and > 30sec) Atrial Fibrilation (AF) Episodes Devices Detected (> 30 Sec) [ Time Frame: 24 months ] [ Designated as safety issue: No ]
    Slow Ventricular Tachycardia will be considered as a tachycardia between 120-150 bpm and > 30sec AF Episodes will be considered as those >30sec

Secondary Outcome Measures:
  • Cardiovascular Mortality Hospitalization Rate Due to Cardiovascular Reasons or Heart Failure [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]

Enrollment: 157
Study Start Date: December 2008

Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
Detailed Description:

The purpose of this observational study is to collect data regarding the population of patients implanted with a St. Jude Medical ICD. Data regarding Slow Ventricular Tachycardia Episodes, Atrial Fibrillation Episodes and the devices programmed parameters will be collected during two years after the implant.
