Implication
Randomized trial examines observer agreement on electrocardiograms in young soldiers, suggesting the need for objective descriptions.
Key Points
- This research aims to evaluate the consistency of electrocardiogram interpretations among different observers.
- Electrocardiograms from 451 young soldiers were independently read by 5 observers.
- 17 records were classified as 'abnormal' by at least one observer, and each underwent reinterpretation without prior knowledge of previous diagnoses.
- The study analyzed variations in the classification of records deemed 'borderline' by observers.
- Observers showed good agreement on 6 marked abnormalities but significant disagreement on lesser deviations among 11 tracings.
- Reinterpretation resulted in between 2 to 9 reclassifications by each observer.
- All observers agreed on the normality of 400 out of 451 records.
