Each panel repesents the data of a single patient. AF was detected in all three patients according to CardioWatch 287-2’s photoplethysmography and single-lead-ECG algorithms, but only twice (top two) according to 24-h Holter. The 24-h Holter period is marked by a red box. The red/blue line represents the photoplethysmography (PPG)-based categorisation based on the Happitech algorithm, where red represents normal sinus rhythm (NSR), and blue represents Afib. Black dots represent the incidences where an ECG was performed. The blue/red dots below the PPG-based diagnosis represent the categorisation made by the Cardiolyse Analytics platform using the single-lead ECG, again red represents NSD, and blue represents Afib.
