“…As in that single previous study, 7 the AV conduction time was prolonged in Fallot patients and it increased over the time, especially from the 10‐year follow‐up time hence the binomial correlation between duration of follow‐up and PR duration. Atrioventricular conduction disorders might have been due to the type of corrective surgery that was performed.…”

“…Little is known about how the electrocardiogram changes with time and the causes of these changes because repeated electrocardiographic follow‐ups of tetralogy of Fallot have been only reported in a single study of 10 patients 7 . In that previous study, first‐degree atrioventricular block was not observed on early postoperative electrocardiograms but a PR duration above 200 msec was noted in 3 of 10 patients at 20‐year follow‐up.…”

“…Even following an initially good postsurgical outcome in TOF, QRS prolongation may progressively occur in later years. Accordingly, regular medical checkups—including electrocardiogram—are of fundamental importance following surgical correction for TOF [8]. It should however be underlined that particular accuracy is required in calculating QRS complex duration at ECG.…”

Tetralogy of Fallot (TOF) is a congenital heart disease frequently treated by surgical repair to relieve symptoms and improve survival. However, despite the performing of an optimal surgical repair, TOF patients are at times characterized by a poor long-term survival rate, likely due to cardiac causes such as ventricular arrhythmias, with subsequent sudden death. In the 80s it was irrefutably demonstrated that QRS prolongation ≥180 msec at basal electrocardiogram is a strong predictor for refining risk stratification for ventricular tachycardia in these patients. The aim of this research was to undertake a review of all studies conducted to assess the impact of QRS duration on the development of life-threatening ventricular arrhythmias in repaired TOF subjects.

“…Conduction disturbances after ToF repair are caused by surgical technique, pulmonary regurgitation, and loss of right ventricular restrictive physiology, leading to dilatation of the right ventricle as well as prolonged QRS duration. 13 Surgical technique was not much different between groups, as most patients underwent TA-TP with trans-annular patch. A previous study reported that the right ventriculotomy technique increased the risk of arrhythmia.…”
