Brief Summary

This study investigates diagnostic performance of a ring-type wearable device for detecting atrial fibrillation. This is a prospective cohort registry study began after the date of IRB approval and until 31th Dec. 2023. The eligible criteria are (1) those who admitted the institution for elective direct-current cardioversion or catheter ablation of persistent atrial fibrillation, (2) those who were successfully converted to sinus rhythm after the intervention, and (3) aged 19 years or more. The exclusion criteria are (1) those aged less than 19 years, (2) those who are not converted to sinus rhythm after the intervention, and (3) those who are not eligible to measure photoplethysmographic signals. This study aims to recruit 100 participants in total. The participants are required to record photoplethysmographic signals by the ring device in addition to routine procedures of direct-current cardioversion or catheter ablation, hence, the study is at minimal risk.

Study Population

The study consecutively recruits participants who admitted for elective direct-current cardioversion or catheter ablation due to persistent atrial fibrillation.

You may qualify if:

  • Those with persistent atrial fibrillation
  • Those who admitted for elective direct-current cardioversion or catheter ablation
  • Those who are successfully converted to sinus rhythm
  • Those who aged 19 years or more

You may not qualify if:

  • Those who aged less than 19 years
  • Those who had other types of cardiac arrhythmias
  • Those who are not eligible to perform electrical cardioversion or catheter ablation
  • Those who are not converted to sinus rhythm
