[Prognostic factors in acute digitalis poisoning].
The prognostic significance of various clinical and biochemical factors was investigated in 179 patients who had ingested more than 2 mg digitoxin. The mortality rate in this series was 17%. Supraventricular arrythmias had no influence on prognosis, but the death risk was higher in males and in patients with AV block. It increased with age, with digitoxin and potassium serum levels and even more with persistent hyperkalemia. Two other factors--previous heart disease and vomiting--were also significant in patients without heart block. Calculated on the basis of 4 clinical factors, the mortality rate varied from 2 to 74%. The death risk in acute digitalis poisoning can therefore be easily assessed simply from clinical criteria.
