Nordenham

This study is performed as an all-case investigation. The treatment is performed based on the SOPs (Appendix Study Protocol). The standard observation period is 3 months from the 1st treatment. Safety and effectiveness are evaluated at 3rd and 12th month. In addition, the extension observation is carried out once a year for 3 years at the longest to collect information on safety and effectiveness as long as CIED treatment continues. When the treatment ends (extraction of all hardware), observation of a patient ends. For each patient, the investigator records data as defined in the protocol at each evaluation point by using a unique Case Report Form (CRF) system. The duration of the study is estimated at 10 years (registry).
