Paced Tricuspid Atresia

Report:

Atrial pacemaker rhythm 111/min

Left axis deviation –60o

Left ventricular hypertrophy with ST/T changes

Comment:

The child had Fontan repair119 (atriopulmonary connection) in infancy.

His combination of LVH and LAD is characteristic of tricuspid atresia; the only thing missing is a large P congenitale. This may of course be masked by atrial pacing.

The pacemaker is a DDD one, with AV interval longer than the present paced PR one; this gives the patient the advantage of narrow, native QRS complex.
