Does a machine learning-based ECG analysis algorithm accurately predict the anatomical origin of idiopathic ventricular arrhythmia in patients undergoing catheter ablation?
A machine learning algorithm using standard 12-lead ECG data can predict the anatomical origin of idiopathic ventricular arrhythmias across 21 possible sites with over 98% accuracy, potentially aiding in pre-procedural planning for catheter ablation.
Zheng et al. (2022) conducted a cohort in Idiopathic ventricular arrhythmia (IVA) (n=545). Machine learning-enabled ECG analysis algorithm vs. Human experts was evaluated on Accuracy of predicting 21 possible sites of IVA origin (Classification scheme 4) (95% CI 97.36-98.71). A machine learning-based ECG algorithm predicted 21 possible sites of idiopathic ventricular arrhythmia origin with an accuracy of 98.24%, outperforming human experts.
