Tricuspid Atresia
Report:
Atrial pacemaker rhythm 111/min (dual chamber pacemaker) 4
Left axis deviation (LAD) –60o 3
LVH with ST/T changes 3
Comment:
A cyanosed child with LAD most likely has tricuspid atresia; in one large series LAD was present in 87% of those with normally related great vessels14.
Also typical is the left ventricular preponderance. It is best to report it descriptively, as LVH with ST/T changes, even though this appearance may have different causes than in adults with LVH.
The pacemaker and the widespread T wave inversion followed surgery. Because of the atrial pacing, the prominent P waves reflecting right atrial enlargement are not in evidence.
