Summary
The Dual Chamber & Atrial Tachyarrhythmias Adverse Events Study (DATAS) was designed to analyze the ability of dual chamber ICDs, to reduce clinically significant adverse events as compared to single chamber ICD in a non selected population with conventional indication of ICD implantation.

Exclusion Criteria
- Permanent atrial fibrillation
