A Gradient Boosted Trees model optimized for ARVC detection achieved an AUC of 0.884 using only ECG data, outperforming a previously reported deep learning model (AUC 0.87).

Does a Gradient Boosted Trees machine learning model improve the detection of arrhythmogenic right ventricular cardiomyopathy?
A Gradient Boosted Trees machine learning model provides high diagnostic accuracy for ARVC, supporting a tiered ML-assisted diagnostic strategy for early triage and confirmatory decision support.
Absolute Event Rate: 0.884% vs 0.87%
p-value: p=< 0.05
< 0.05), while differences vs the remaining five models were not statistically significant. The next-best model (Random Forest) showed a minimal performance gap (ΔAUC = 0.008), whereas low-ranked models showed larger deficits (ΔAUC = 0.040-0.042). An ECG-only version of the GBT model achieved an AUC of 0.884, exceeding the previously reported ECG-deep learning waveform model (AUC = 0.87). GBT performs best among evaluated algorithms and offers clinically interpretable feature relevance consistent with task force criteria for ARVC diagnosis. An ECG-only deployment supports early triage, while the multimodal model functions as confirmatory decision support after advanced testing. These findings support a tiered ML-assisted diagnostic strategy for ARVC and justify prospective external validation in broader clinical settings.
Quansah et al. (Thu,) conducted a observational in Arrhythmogenic right ventricular cardiomyopathy (ARVC). Gradient Boosted Trees (GBT) machine learning model vs. Other machine learning models (e.g., Random Forest, deep learning) was evaluated on Area under the curve (AUC) for ARVC detection (p=< 0.05). A Gradient Boosted Trees model optimized for ARVC detection achieved an AUC of 0.884 using only ECG data, outperforming a previously reported deep learning model (AUC 0.87).
