Key result
A simple ECG algorithm using only the R/S ratio in leads V1, V2, and aVF accurately localized accessory pathways with an overall sensitivity of 94% and specificity of 98%.
Why the study?
Does a simple ECG algorithm using only the R/S ratio accurately localize accessory pathways in patients with Wolff-Parkinson-White syndrome?
Observational (n=142)
Does a simple ECG algorithm using only the R/S ratio accurately localize accessory pathways in patients with Wolff-Parkinson-White syndrome?
A simple ECG algorithm using only the R/S ratio in leads V1, V2, and aVF provides high sensitivity and specificity for localizing accessory pathways in WPW syndrome.
No takes yet. Share an insight, caveat, or question.
May simplify accessory pathway localization in WPW; leaves open prospective validation before practice change.
Taguchi et al. (2013) conducted an observational in Wolff-Parkinson-White syndrome (n=142). R/S ratio-based ECG algorithm vs. Fluoroscopic anatomy (successful ablation sites) was evaluated on Algorithm sensitivity and specificity for localizing accessory pathways. A simple ECG algorithm using only the R/S ratio in leads V1, V2, and aVF accurately localized accessory pathways with an overall sensitivity of 94% and specificity of 98%.
