RESUMEN
We describe the case of a 28-year-old man from Greece with Opistorchis felineus infestation. The patient presented with intense abdominal pain, bilious emesis and eosinophilia. He probably acquired the infection overseas, since he was a commercial airline pilot who used to fly to endemic areas and to consume raw or undercooked fish. He was successfully treated with praziquantel administered in divided doses over a single day. Opisthorchiasis is common to eastern Europe and areas of the former Soviet Union, but extremely rare in Greece. Medical personnel should be cognizant of this parasitic infection, since world travel can spread it to areas of the world unaccustomed to it.

The electrocardiograms of 29 patients with atrial fibrillation and aberrancy (Ashman phenomenon) were studied. The length of the cycles manifesting aberrancy (R-RA) varied from 270 to 520 msec (mean 372 +/- 55). It correlated negatively with the heart rate (r-0.899, p less than 0.001) and for equal heart rates in separate persons it varied with the length of the preceding R-R cycle (p less than 0.01). Above a critical R-RA length of 520 msec and outside an R-R/R-RA ratio range of 1.5-3.6 aberrancy is never observed: this finding is important for the differentiation of aberrancy from ventricular ectopy.
