Does Doppler echocardiography accurately estimate invasively measured systolic pulmonary arterial pressure in mountaineers at high altitude?
Doppler echocardiography provides an accurate and reproducible estimation of systolic pulmonary arterial pressure at high altitude, correlating closely with invasive measurements.
Allemann et al. (2000) studied this question.
