Key result
Morphological Component Analysis with index thresholding achieves ~86% accuracy for detecting PVCs.
Morphological Component Analysis provides an interpretable and accurate method for detecting premature ventricular contractions in ECG signals, achieving 85.7% accuracy.
Answers are grounded in this paper and cite their sources.
May support automated PVC detection algorithms in ECG research; leaves open prospective clinical validation.

Faccin et al. (2026) studied Arrhythmia (Premature Ventricular Contractions) (n=8). Morphological Component Analysis (MCA) and index thresholding vs. Other classification methods (MoE, LDA, ANN, FLP) was evaluated on Classification accuracy for normal vs non-normal (ventricular) beats. Morphological Component Analysis combined with index thresholding achieved an overall classification accuracy of 85.7% and sensitivity of 89.2% for detecting premature ventricular contractions.
