Key result
In patients with Wolff-Parkinson-White syndrome, epicardial activation sequences were well reflected by the location of the QRS initial minimum, mid-QRS isochrone movement, and terminal maximum on body surface maps.
Why the study?
How do epicardial excitation propagation patterns correlate with body surface map indices in patients with Wolff-Parkinson-White syndrome?
Observational (n=39)
How do epicardial excitation propagation patterns correlate with body surface map indices in patients with Wolff-Parkinson-White syndrome?
Body surface mapping accurately reflects epicardial excitation propagation in WPW syndrome, with initial QRS minima and late QRS maxima corresponding to early and final excitation sites, respectively.
Body surface mapping may localize accessory pathways in WPW; leaves open whether it improves ablation success over standard ECG.

Kamakura et al. (1995) conducted an observational in Wolff-Parkinson-White syndrome (n=39). Body surface mapping vs. Epicardial mapping was evaluated on Correlation between epicardial activation sequence and body surface maps. In patients with Wolff-Parkinson-White syndrome, epicardial activation sequences were well reflected by the location of the QRS initial minimum, mid-QRS isochrone movement, and terminal maximum on body surface maps.
