| Zusammenfassung | Participants in the seventh annual PhysioNet/CinC Challenge developed and evaluated methods for measuring the QT interval, using the 549 records of the PTB Diagnostic ECG Database. Fifteen entrants entered sets of manually reviewed measurements, and the record-byrecord medians of these defined the 549 “gold standard” reference QT measurements. Twenty-five entrants submitted sets of automatically-derived measurements. All entrants were allowed to omit records considered unreadable. Each entry received a score, calculated as the RMS error in milliseconds (relative to the reference QT measurements) divided by the fraction of records measured. The best scores for manual and automated entries were 6.67 ms and 16.34 ms respectively; typical scores were 10-20 ms for manual entries and 20-30 ms for automated entries. Significantly, a meta-entry derived from the medians of six automated entries achieved a score of 10.93 ms, better than all but four manual entries. |
