Discriminating between atrial fibrillation and sinus rhythm in physiological signals obtained from video

摘要: What is disclosed a system and method for determining whether subject in atrial fibrillation. A video received of region exposed skin subject. The acquired where videoplethysmographic (VPG) signal can be registered by at least one imaging channel device. For each batch image frames, pixels associated with the are isolated processed to obtain time-series signal. VPG extracted from power spectral density (PSD) computed across all frequencies within pulse harmonic strength (PHS) calculated this compared discrimination threshold, defined herein. determination made fibrillation or normal sinus rhythm.
