[Antidigoxin Fab-fragments in suicidal digoxin poisoning. Successful treatment of recurrent ventricular fibrillation].

A 49-year-old woman took about 12.5 mg digoxin with suicidal intent. Severe arrhythmias, including recurrent ventricular fibrillation, occurred. Sheep Fab fragments of digoxin-specific antibodies were administered i. v. at a dose of 480 mg. Serum free-digoxin concentration fell within half an hour to 0, with simultaneous rise of total digoxin from 13 micrograms/l to a maximum of 176 micrograms/l after 2 hours. At the same time there was marked improvement in the clinical condition with restoration of a stable sinus rhythm. There were no side effects to the Fab fragment administration.
