  • Patients who participated in the BIOSync study\*.
  • Patients with a dual-chamber pacing system equipped with the CLS algorithm. \* If needed, inclusion of other patients who did not participate in the BIOSync study will be considered to complete study cohort, provided that they have already a CLS pacemaker system and fulfill the same inclusion/exclusion criteria of the BIOSync study.
