Cardiac Tamponade on Subcostal 4 Chamber POCUS Echocardiogram Which of the following would be expected in this patient? Resolution: >25% E wave respiratory variation. The clip shows RV collapse during diastole, supporting tamponade physiology. A >25% decrease in mitral valve inflow (E wave) during inspiration (US evidence of pulsus paradoxus) would be expected, as well as a plethoric IVC.
