Pulsus paradoxus is an exaggerated fall in systolic blood pressure with inspiration (usually greater than 10 mm). Understanding the accuracy of pulsus paradoxus for a diagnosis of cardiac tamponade requires a consideration of the mechanisms underlying its genesis, and a knowledge of its presence in other conditions and its variable absence in cardiac tamponade with associated disease states. Echocardiography (M-mode, 2-D, and Doppler) has aided considerably our understanding of pulsus paradoxus… CONTINUE READING
