<b><u>Does This Patient Have Pericardial Tamponade?</u></b></p>
<ul>
<li>
Echocardiography is critical for the identification of a pericardial effusion and rapid diagnosis of pericardial tamponade.</li>
<li>
Common echocardiography findings that suggest tamponade include diastolic right ventricular collapse, systolic right atrial collapse, a plethoric IVC with minimal respiratory variation, and potentially exaggerated respiratory cycle changes in mitral and triscupid inflow velocities.</li>
<li>
Of these,<strong> systolic right atrial collapse is the earliest echocardiographic sign of tamponade</strong><strong>, </strong>with a sensitivity ranging from 50% to 100%.</li>
<li>
Of the 4 standard echo views, systolic right atrial collapse can best be viewed in the apical 4-chamber and subxiphoid views.</li>
