title: Foxed by the foxglove.
abstract: The art of general practice is to identify important causes of common, often undifferentiated symptoms. This article presents two cases of clinical digoxin toxicity in the presence of normal or low serum digoxin levels. Standard teaching says that symptoms are related directly to toxic serum levels, but this appears to be not always the case.
