Fig. 1 Two-dimensional echocardiograms (apical four-chamber view). A, Small pericardial effusion (PE) (arrow). B, PE (arrow) was larger 3 weeks later when patient had cardiac tamponade. LA = left atrium; LV = left ventricle; RA = right atrium; RV = right ventricle.

Fig. 2 Pulsed wave Doppler signal (at leaflet tips) of mitral inflow recorded with respirometry (Resp) done at same time two-dimensional echocardiographic images (Fig. 1) were obtained. A, Stable diastolic signal of early (E) and late (A) filling throughout respiratory cycle. B, Attenuated early filling velocity (small arrowhead) immediately after onset of inspiration (Insp) that increases (large arrowhead) after onset of expiration (Exp). This pronounced respiratory variation in inflow signal is characteristic of cardiac tamponade.1 Mayo Clinic Proceedings 1997 72, 33-36DOI: (10.4065/72.1.33) Copyright © 1997 Mayo Foundation for Medical Education and Research Terms and Conditions
