Key result
ECG algorithms yield low accuracy of ~37% for localizing accessory pathways in WPW syndrome.
Why the study?
Several electrocardiographic algorithms exist to locate the accessory pathway in WPW syndrome, but their comparative accuracy in identifying AP location is unclear.
Cross-Sectional (n=111)

ECG algorithms' low accuracy cautions against sole reliance for pathway localization; challenges routine use and leaves open better noninvasive methods.
Teixeira et al. (2016) conducted a cross-sectional in Wolff-Parkinson-White syndrome (n=111). Electrocardiographic algorithms vs. Electrophysiological study was evaluated on Overall absolute accuracy of the algorithms in identifying the exact location of the accessory pathway. Seven electrocardiographic algorithms demonstrated a low overall absolute accuracy ranging from 27% to 47% in precisely localizing the accessory pathway in patients with Wolff-Parkinson-White syndrome.
