Brief myocardial ischemia of less than 20 min duration, followed by reperfusion, is known to cause transient contractile dysfunction, often termed myocardial stunning. Tagged magnetic resonance imaging offers a noninvasive method that can be used to quantify this regional mechanical dysfunction in stunned myocardium. To this end, a closed-chest canine model of myocardial stunning was created by...

Left bundle branch block or ventricular paced rhythms can sometimes make acute myocardial ischaemia difficult to diagnose in the 12-lead ECG. Several algorithms for diagnosing ST segment elevation myocardial infarction have been described with different sensitivity and specificity. The 12-lead ECG may also serve as a valuable tool in evaluating and diagnosing pacemaker dysfunction. We present a...

introduction epstein-barr  virus  (ebv)  infection  can  present  with  a  variety  of  manifestation. case report  here  we  present  a  case  of  a  7  year- old  immunocompetent  girl  who  came  with  acute  abdominal  pain ,  had  echocardiographic  evidence  of  myocardial  dysfunction  and  finally  was  diagnosed  as  a  case  of  serologically  proven  acute  ebv  infection. conclusion...

A 39 year old man with postoperative constrictive pericarditis after pericardiectomy developed major left ventricular systolic dysfunction with an anterior wall infarct pattern on ECG but no regional wall motion abnormalities by echocardiography or serum enzymatic evidence of a myocardial infarction. The left ventricular dysfunction resolved over two weeks with supportive treatment. It is postu...
