Figure 3From: Acute ST segment elevation during exercise stress echocardiography due to severe pulmonary hypertension Continuous wave Doppler across tricuspid valve at rest (A), stress (B) and recovery (C). The estimated PASP (ΔP = 4V2+RAP, where V is the tricuspid regurgitation velocity and RAP is the estimated right atrial pressure of 10 mmHg) is 46 mmHg at rest, 81 mm Hg during stress and 101 mm Hg immediately post stress.Back to article page
