Computer-implemented method for generating an annotated photoplethysmography (PPG) signal

Computer-implemented method for generating an annotated photoplethysmography (PPG) signal

A computer-implemented method for generating an annotated photoplethysmography signal (402), comprises: - recording (101) an electrocardiogram or ECG signal (201); - recording (102) a photoplethysmography or PPG signal (202), semi- synchronously with the recording (101) of the ECG signal (201); - an...

Zusammenfassung:A computer-implemented method for generating an annotated photoplethysmography signal (402), comprises: - recording (101) an electrocardiogram or ECG signal (201); - recording (102) a photoplethysmography or PPG signal (202), semi- synchronously with the recording (101) of the ECG signal (201); - annotating (103) segments in the ECG signal (201) either algorithm-based or expert-based; - time-aligning (104) the PPG signal (202) and the ECG signal (201); - detecting (105) ECG beats (301) in the ECG signal (201); - detecting (106) PPG beats (302) in the PPG signal (202); - pairing (107) the ECG beats (301) onto the PPG beats (302); - deriving (108) annotations for PPG signal segments based on the nature of the ECG segment annotations and on how the ECG beats (301) can be paired with the PPG beats (302); and - annotating (109) the PPG signal segments using the annotations, thereby generating the annotated PPG signal (402).
