In this case, electrophysiology and histology could be studied in the same heart. Clinical investigation, clinical electrophysiology, and postmortem serial histological sections of the septum were analyzed. Methods A patient with repeated seizures and a short PR interval with narrow QRS complex underwent electrophysiologic studies. Results The patient died while experiencing a very rapid supraventricular tachycardia and histologic examination showed a atrio‐hisian bypass tract. Conclusion In our study, the lack of lengthening of the PR interval in spite of progressively premature atrial stimulation connected with the presence of atrio‐hisian bypass tract.
