Echocardiographic probability of pulmonary hypertension⁵

RVSP (mm Hg)	Peak tricuspid regurgitation velocity (m/s)	Other ECHO PAH sign	ECHO probability of PAH
31	2.8 or not measurable	No	Low
31	2.8 or not measurable	Yes	Intermediate
32–46	2.9–3.4	No	Intermediate
32–46	2.9–3.4	Yes	High
>46	>3.4	Not required	High

ECHO, echocardiography; PAH, pulmonary arterial hypertension; RVSP, right ventricular systolic pressure.
