A 2 year old presents with cyanosis. His ECG is given.

What is the diagnosis?

 
The importance of determining the QRS axis lies in coming to a conclusion regarding specific diagnosis of the cardiac anomaly rather than in ventricular hypertrophy.
Sinus rhythm is present { with axis of 15-20°}. P amplitude and duration is normal, with p axis of 42°.PR interval is 0.12 sec and normal. QRS duration is 0.09 sec and QTc is 0.40 sec, QRS axis is – 35 degrees { left anterior hemiblock or superior axis } and T axis is approximately 112 °. R wave in aVL {17 mm } and is abnormal for age.
The QRS axis is about – 35°, the diagnosis would be ASD of the primum type {atrioventricular canal defect}, Single ventricle, Tricuspid atresia or Ebsteins anomaly .
