paradoxic pulse

(redirected from pulsus respiratione intermittens)

par·a·dox·ic pulse

an exaggeration of the normal variation in the systemic arterial pulse volume with respiration, becoming weaker with inspiration and stronger with expiration; characteristic of cardiac tamponade, rare in constrictive pericarditis; so called because these changes are independent of changes in the cardiac rate as measured directly or by electrocardiogram.

Pulsus paradoxicus Cardiology A ↓ of ≥ 10 mm Hg in systolic BP on inspiration, a finding which, like the Kussmaul sign–an abnormal ↑ instead of a ↓ in jugular venous pressure with inspiration, suggests cardiac tamponade–impaired diastolic filling of the heart due to ↑ intrapericardiac pressure Clinical Air hunger, cyanosis, visible distension of neck veins
