ECG results are often abnormal in patients with PAH, revealing right atrial enlargement, right axis deviation, right ventricular hypertrophy, and characteristic ST depression and T-wave inversions in the anterior leads. Sometimes, an incomplete RBBB may be seen (usually in patients with atrial septal defects). However, some patients with IPAH have few or no abnormal ECG findings. Thus, normal ECG results do not exclude a diagnosis of PAH.
