Although pericarditis and pericardial effusion are common cardiac complications of systemic lupus erythematosus (SLE), cardiac tamponade is a very rare initial manifestation of this disease. We describe a case of a young male patient in whom cardiac tamponade secondary to a loculated pericardial effusion was the presenting symptom of SLE.

Lyme disease may present with a variety of cardiac manifestations ranging from first degree to third degree heart block. Cardiac involvement with Lyme disease may be asymptomatic, or symptomatic. Atrioventrical conduction abnormalities are the most common manifestation of Lyme carditis. Less common, are alternating right bundle branch block (RBBB) and left bundle branch block (LBBB). We present...

Intuitively, dynamic visual stimuli, such as moving objects or flashing lights, attract attention. Visual search tasks have revealed that dynamic targets among static distractors can indeed efficiently guide attention. The present study shows that the reverse case, a static target among dynamic distractors, allows for relatively efficient selection in certain but not all cases. A static target ...

Although pericarditis is the most frequent cardiac involvement in systemic lupus erythematosus (SLE), cardiac tamponade is very rare as an initial manifestation of this disease. We report the case of a 27-year-old patient in whom the diagnosis of SLE was discovered during cardiac tamponade.

A one-month-old male terrier dog was referred in shock status with a history of anorexia, tachypnea, abdominal distention and progressive weight loss. Auscultation of right side of the lungs found enhanced respiratory noises. The thorough auscultation of the opposite side of the chest revealed the presence of typical intestinal sounds. Cardiac auscultation revealed muffled heart sounds and a di...

A 54-year-old woman with transient global amnesia (TGA) was found to have digitalis-induced bradyarrhythmia with atrioventricular dissociation. The amnesia cleared only upon resolution of the arrhythmia. Cardiac arrhythmia has been postulated as a cause, but TGA in the setting of cardiac arrhythmia has not been documented previously. Cardiac arrhythmia should be excluded in patients with TGA, a...
