Oct 15, 2010 · Negative delta wave and QRS in II, III and aVF suggests posteroseptal pathway (Ref: Algorithm in Figure 35-19, Libby: Braunwald’s Heart Disease, 8th Edition). Wolff-Parkinson-White (WPW) syndrome results from preexcitation of the ventricles through AV bypass tracts or accessory pathways.

Dec 12, 2022 · Our novel 12-lead ECG-based EASY-WPW algorithm enables reliable and accurate pre-interventional AP-ablation site determination in adults and children. Only two steps are necessary to locate left-sided AP and three steps to determine right-sided AP.

Feb 4, 2022 · Wolff-Parkinson-White (WPW) Syndrome is a combination of the presence of a congenital accessory pathway and episodes of tachyarrhythmia.

Sep 17, 2008 · Generally if there is a positive delta wave in lead II with negative delta waves in III and aVF, it is likely that the posteroseptal accessory pathway will be located in a more right-sided (possibly right posterior/posterolateral) location.

Oct 12, 2010 · WPW syndrome results from tachycardia associated with an accessory pathway. The WPW pattern is diagnosed by a delta wave and/or short PR interval on an ECG. Once symptomatic, patients can be treated with catheter ablation or …

Wolf–Parkinson–White (WPW) syndrome is a disorder characterized by the presence of at least one accessory pathway (AP) that can predispose people to atrial/ventricular tachyarrhythmias and even sudden cardiac death.

Feb 21, 2019 · Indeed, Wolff-Parkinson-White (WPW) syndrome may be demonstrated as a concomitant diagnosis in up to 10% of Ebstein’s anomaly patients. In Ebstein’s anomaly, the posteroseptal location is second most frequent behind the right free wall group.

It is important for a successful and safe ablation to evaluate coronary vein anomalies in patients with left posterior and posteroseptal accessory pathways. <Learning objective: In pediatric patients, Wolff–Parkinson–White syndrome with the posteroseptal accessory pathway with coronary sinus diverticulum is rare.

The vast majority of posteroseptal accessory pathways ("typical") are epicardial and ablated by dissection of the posteroseptal region. Rarely, posteroseptal accessory pathways are "atypical" in that they are intraseptally located near the AV node on the left atrial endocardial surface.

An accessory pathway, bundle of Kent, exists between atria and ventricles and causes early depolarisation of the ventricle. The location of the pathway may be deduced as follows:- Thank you to Soren Strange MD, Department of Cardiology, Frederiksberg Hospital, Denmark for providing this recording.
