REal-worLd vAlidaTION of PhotoPlehtysmoGraphy (for Atrial Fibrillation Detection) (RELATION PPG)

October 23, 2023 updated by: Ziekenhuis Oost-Limburg

A Real-World Validation Study of Intermittent Photoplethysmography Based Rhythm Monitoring for Atrial Fibrillation Detection

Mobile health solutions for rhythm monitoring (e.g. atrial fibrillation detection) using photoplethysmography (PPG) technology on a smartphone have been developed. This study validates the performance of a digital health application (FibriCheck®) using PPG technology on a smartphone against a single-lead ECG device (Kardia Mobile®).

  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Study group
All subjects will perform heart rhythm measurements with both diagnostic tests.
Measurements are performed twice daily, starting 4 weeks before a pulmonary vein isolation procedure (PVI) and ending 4 weeks after the PVI.
Measurements are performed immediately before and after every FibriCheck® measurement.
