Abstract

Renal replacement therapy, such as hemodialysis, is the only effective treatment for the end-stage renal disease. Hemodialysis is directly associated with significantly increased risk of developing atrial fibrillation (AF). Since physicians must stop the procedure of hemodialysis when AF occurs, timely detection of AF is crucial. Electrocardiography could provide a reliable way for AF monitoring, but due to a routine of the procedure, it is not convenient enough for hemodialysis patients. Furthermore, electrocardiography increases the costs due to increased workload of medical staff. Therefore, as an alternative, we present a concept of unobtrusive AF monitoring during hemodialysis. The proposed system covers both hardware and software: a wearable device, capable of recording photoplethysmogram (PPG), and an online low complexity AF detection algorithm, applied for decision making. We tested this system on a pre-recorded PPG, containing both AF and normal rhythm episodes. Results show that the low power unobtrusive PPG wearable device has a potential to be applied for real-time AF detection using solely the PPG.
