Medical image of the week: pulsus paradoxus
A 75 year-old man was admitted for suspected septic shock and acute renal failure requiring hemodialysis. He did not required mechanical ventilation. An arterial line was placed and he was found to have pulsus paradoxus (Figure 1). A transthoracic echocardiogram showed early right atrial diastolic c...
