Case presentation

These tracing belongs to a 46-year-old woman, carrier of Ebstein’s anomaly, admitted in the emergency room with atypical chest discomfort and palpitations, without risk factors for coronary artery disease, normal biomarkers, and serial unaltered ECGs.
The first tracing is similar to the prior ones made over the last 7 years. This one was made immediatly after cardioversion (there are no artifacts).

All the ECGs in her history show the same pattern.
She displays Wolff-Parkinson-White with frequent paroxysmal palpitations.
Five years ago ablation was proposed to her; however, the patient refused the procedure afraid of complications.


Is this notch inside of QRS: is this a J wave?

Is a conduction disorder? or is part of a giant wave P?

What do the colleages think? Already underwent one unsuccessful ablation
