What ECG findings are typically seen in patients with idiopathic pulmonary artery hypertension?
1) Frequent premature ventricular complexes
2) Right-axis deviation
3) Right ventricular hypertrophy
4) Left bundle-branch block

Question

Quizplus · Accepted Answer

Patients with idiopathic pulmonary artery hypertension typically have right ventricular hypertrophy on ECG, which is represented by an increased R wave amplitude in leads V1-V4 and a rightward shift or prominence of the QRS axis. Left bundle-branch block is not commonly seen in this population. Premature ventricular complexes may occur but are not a consistent finding. Therefore, the best choices are options 2 and 3.
