Patients with central alveolar hypoventilation, COPD, and OHS may show evidence of pulmonary hypertension from examination findings. These findings include a narrowly split and loud pulmonary component (P2) of the second heart sound, a large a-wave component in the jugular venous pulse, a left parasternal (right ventricular) heave, and an S4 of right ventricular origin. A diastolic murmur indicative of pulmonic valve regurgitation may be auscultated.
