Key result
Magnetocardiographic mapping localizes abnormal ventricular activation within ~2.1 cm of successful catheter ablation sites.

Supports feasibility of magnetocardiographic mapping for ventricular ectopy localization; leaves open clinical utility without prospective validation.
Observational (n=49)
Does magnetocardiographic mapping accurately localize the origin of ventricular ectopic beats compared to successful catheter ablation sites in patients with WPW syndrome or coronary artery disease?
Mean Difference: 2.1
Magnetocardiographic mapping can localize the origin of ventricular ectopic beats with a mean 3D spatial difference of 2.1 cm compared to successful catheter ablation sites.
Oeff et al. (1994) conducted an observational in Wolff-Parkinson-White syndrome and coronary artery disease (n=49). Magnetocardiographic mapping vs. Catheter ablation site was evaluated on Mean difference in space between magnetocardiographic localization and successful catheter ablation site (MD 2.1 cm). Magnetocardiographic mapping localized the origin of abnormal ventricular activation with a mean 3D spatial difference of 2.1 +/- 1.7 cm compared to successful catheter ablation sites.
