Additionally to ECG Colour-Tissue Doppler Imaging can help to localize the pathway, even in concealed WPW.

Hope it is helpful

Just look for preexcitation syndromes.

Hi Leonard

http://lifeinthefastlane.com/ecg-library/pre-excitation-syndromes/

Have you come across Life in the fast lane - Australian website covering ECG interpretation and much more instead.

There are some good DVDs attached.  Apparently up to 8 types of WPW have been identified. For me Types A, B and C are more than enough.

Excellent website

Hope it proves helpful

contact Finapres in Netherlands. They have an algorithm

Marriott's Practical Electrocardiography 12th edition.  This text has been around for over 4 decades and is still widely used to teach ECG interpretation at an advanced level.  See chapter 7 on preexcitation syndromes and diagnosis.

Arruda et al is a bit complicated but most tested one.  I look at the delta wave direction (positive/up or negative/down).  Start with V1- eg if delta wave positive, then probably left sided pathway with preexcited wave front heading toward V1.  Then inferior leads tell you about anterior/posterior- eg negative delta waves suggest a posterior origination.  Then Lead I and L give you septal/lateral- eg if delta wave positive then think septal pathway (wavefront heading toward lateral wall).

you could also choose an algorithm from fitzpatrick et al

HI LEONARD

I ATTACH  ONE PAPER IN PORTUGUESE AND OTHERS ALGORHYTHMS FOR WPW . BAYÉS DE LUNA AND ARRUDA INCLUDED

ALL THE BEST

Try this article: Chiang,C et al: An Accurate Stepwise Electrocardiographic Algorithm for Localization of Accessory Pathways in Patients with WPW from a comprehensive analysis of Delta Waves and R/S ratio during sinus rhythm.  Am J Cardiol 1995; 76:40-46.      Please note that best result is when there is max preexitation for the delta waves.

Delta Waves are specific for WPW.
