RESUMO
A patient with previous actual atrial flutter had what appeared to be atrial flutter seen on Holter monitoring during treatment with a transcutaneous electrical nerve stimulation (TENS) unit. This proved to be artifact caused by the unit rather than a true arrhythmia. The artifact was reproduced in a normal volunteer by application of a TENS unit.

An 18-year-old patient underwent repair of traumatic aortic pseudoaneurysm. Postoperatively, the physical examination showed hypertension with 30 mm Hg gradient between the upper and lower extremities. Doppler echocardiographic evaluation demonstrated a new (secondary) aortic coarctation at the site of the repair. Transesophageal echocardiography revealed the detailed anatomy and the cross-sectional area of the coarctation.
