Figure 2 (A) Simultaneous echocardiography (left side of the panel, apical four-chamber view) and electrocardiogram recordings (right side of the panel) in a 64-year-old man who developed significant pericardial effusion (PE) with signs of cardiac tamponade three weeks after mitral valve replacement. Note the reduction of the QRS amplitude in the limb leads and concomitant nonspecific T wave abnormalities. (B) Same patient as in (A) after successful pericardiocentesis with removal of 600 ml of pericardial fluid. Note the even lower QRS voltage in the limb leads than before pericardiocentesis and the persistence of nonspecific T wave abnormalities. (C) Same patient six days after pericardiocentesis. The echocardiogram shows no evidence of recurrent effusion. QRS amplitude in the limb leads significantly increased. LV = left ventricle; RV = right ventricle.
