Key result
Multivariate classification of pediatric ECGs yields ~6% higher diagnostic accuracy than conventional deterministic methods.
Why the study?
Statistical multivariate and conventional deterministic methods of computerized ECG interpretation in pediatric orthogonal ECGs have not been directly compared for diagnostic accuracy.
Does a statistical multivariate classification method improve diagnostic accuracy compared to a conventional deterministic method in the computer interpretation of pediatric orthogonal ECGs?
Population

Does a statistical multivariate classification method improve diagnostic accuracy compared to a conventional deterministic method in the computer interpretation of pediatric orthogonal ECGs?
Absolute Event Rate: 85% vs 79%
Statistical multivariate techniques provide better classification results than conventional deterministic analysis for pediatric ECG interpretation, though combining both methods may further improve diagnostic accuracy.
Brohet et al. (1984) conducted a cross-sectional in Congenital heart disease and ventricular hypertrophy (n=1,711). Statistical multivariate classification method vs. Conventional deterministic classification method was evaluated on Overall accuracy of multigroup ECG diagnosis. Statistical multivariate classification of pediatric orthogonal ECGs yielded higher overall diagnostic accuracy compared to conventional deterministic methods (85% vs 79%).
