Atrial flutter as a manifestation of digitalis toxicity

Although digitalis overdosage is known to produce a variety of atrial, junctional, and ventricular arrhythmias, atrial flutter due to digitalis intoxication has been rarely reported. The present paper reviews the literature and reports what appears to be the sixteenth case. The available information on the accepted cases of atrial flutter due to digitalis toxicity has been analyzed for clues as to when digitalis can be considered the cause of the flutter.
