In patients with PAH, JVP is typically elevated with a prominent A wave seen. A prominent V wave may be seen with severe right ventricular failure and significant tricuspid regurgitation.
Other findings on physical examination include:
Right-sided S4 with left parasternal heave
Holosystolic murmur of tricuspid regurgitation
Wide splitting second heart sound with increased intensity
Splenomegaly is rarely present in PAH but may be seen in PAH owing to schistosomiasis.
