Key result
Magnetocardiography localized accessory pathways in WPW patients within an average of 2.1 cm (range 0-5 cm) of the sites determined by invasive catheter mapping.
Why the study?
Does magnetocardiography accurately localize accessory pathways compared to invasive catheter mapping in patients with Wolff-Parkinson-White syndrome?
Observational (n=7)
Does magnetocardiography accurately localize accessory pathways compared to invasive catheter mapping in patients with Wolff-Parkinson-White syndrome?
Effect estimate: 2.1 cm on average
Magnetocardiography using a multichannel system shows promise as a non-invasive method for localizing accessory pathways in WPW patients, with an average accuracy of 2.1 cm compared to invasive mapping.

May support non-invasive accessory pathway localization in WPW; leaves open clinical adoption pending prospective validation.
Weismüller et al. (1992) conducted an observational in Wolff-Parkinson-White syndrome (n=7). Magnetocardiography (MCG) vs. Invasive catheter mapping was evaluated on Distance between magnetocardiographic localization and catheter mapping (2.1 cm on average). Magnetocardiography localized accessory pathways in WPW patients within an average of 2.1 cm (range 0-5 cm) of the sites determined by invasive catheter mapping.
