Background Few studies have examined QT, JT interval, and ST-segment changes due to radiofrequency catheter ablation (RFA) in manifest Wolff–Parkinson–White (WPW) syndrome in pediatric patients.Methods The study involved 27 patients (male-to-female, 13:14; age, 12 (5–16) years) who were diagnosed with WPW syndrome and underwent RFA in our hospital between 2009 and 2022. Electrocardiographic (ECG) changes were compared between the group with ventricular preexcitation due to an accessory pathway (manifest group, n = 16) and those without it (concealed group, n = 11).Results The QT interval before RFA was significantly longer in the manifest group than in the concealed group (402 [362–482] vs. 344 [323–427]; p = 0.001). The QT interval was significantly shortened in the manifest group before and after RFA (402 [362–482] vs. 360 [298–422] msec; p = 0.01). At 1 month, the QT interval difference between the manifest and concealed groups disappeared (366 [305–437] vs. 335 [301–436] msec; p = 0.001). ST-segment changes were found after RFA in 63% (10/16) of the patients in the manifest group but not in the concealed group. ECG changes presenting the Brugada-pattern were found in two patients. One month later, ECG abnormalities persisted in only one patient.Conclusions In cases of prolonged QT interval or ST-segment abnormalities lasting > 1 month after RFA, the coexistence of manifest WPW syndrome with long QT syndrome or Brugada syndrome may be considered.

“…The first three rows correspond to the DII electrocardiographic leads V1 and V5, and the following four intracavitary proximal AV junction, AV junction distal ablation catheter and right ventricle (Figure 6). In many more occasions that we can think, Wolff-Parkinson-White can go together to other cardiac electrical disease [10]. The cryptogenic Wolff-Parkinson -White is not uncommon.…”

“…The measures of the different intervals give us shorter lengths for the PR and QTc-intervals on the same ECG tracing (Breijo pattern) [1] (Figure 3). Namely, a Breijo pattern associated to a Wolff-Parkinson-White pattern on the same ECG tracing [1][2][3][4][5].…”

In 2008, Breijo-Márquez [1] published an article in the "International Journal of Cardiology", whose content was the description of an ECG pattern unknown to date. This pattern consisted of a shortening of PR and QT-intervals in the same individual (on an ECG tracing). The article was entitled by the author as "Decrease of electrical cardiac systole". Since then, another many cases with same ECG features have been assessed and diagnosed.So much so that, we think that all symptoms-by milder that Volume 5 Issue 3 -2016
