May aid ECG differentiation of tricuspid from pulmonary atresia in neonates; leaves open prospective validation.
What are the differentiating electrocardiographic features between tricuspid atresia and pulmonary atresia with intact ventricular septum?
Electrocardiography reveals distinct patterns, such as biatrial hypertrophy and left axis deviation, that help differentiate tricuspid atresia from pulmonary atresia with intact ventricular septum.
Gamboa et al. (1966) studied this question.
