Illustrations of episode detection method performance.
Examples of detected episodes (highlighted in yellow) and clinician’s annotations (highlighted in gray) overlayed onto heart rate, in beats per minute (bpm) tracings. 5A illustrates good performance with only small timing differences between annotated and detected episodes, and the majority of episodes are overlapping. 5B provides an example of a low-precision period, defined as detected episodes that were not annotated by the clinician (false positives). 5C illustrates a low-recall scenario, where clinician-annotated episodes were not detected by our methods (false negatives).
