An investigation of the contextual distribution of false positives in a deep learning-based atrial fibrillation detection algorithm

作者:

Highlights:

• Showed how an AF detection model results in high FPR under free-living conditions.

• Investigated the influence of user’s ambulatory contexts on FPR on 215 days long ECG.

• Sudden Acceleration, activity & body position changes cause 78% of short FP segments.

• True positive AF segments were clustered around the morning and late evening hours.

• Provided the implications of context-awareness for improving ambulatory AF detection.
