In repaired tetralogy of Fallot (rTOF), the septal anatomical isthmuses (AI), 3, between the ventricular septal defect (VSD) and pulmonary annulus, and 4, between the VSD and tricuspid annulus, are important ventricular tachycardia (VT) substrates when slow conducting.

Crochetage sign on ECG in ASD ECG in ASD with severe pulmonary hypertension: Tall R’ in V1, ST depression in inferior leads and V2-V5, and T inversion in inferior leads and V1-V6 are seen. The sign has been described in VSD with biventricular hypertrophy in children. Himalayan P waves are also described in tricuspid atresia.

And that will be the approximate level of the tricuspid valve, the reference point for measuring right atrial pressure. In right atrial tracing, this occurs at the time of right ventricular contraction, with bulging upwards of the tricuspid valve. The Y descent is shallow in tricuspid stenosis, and absent in cardiac tamponade.
