Serum digoxin estimations were done in 98 patients receiving digoxin for heart failure of
varied aetiology. Digoxin toxicity or the lack of it was determined on the basin of established …

Serum and myocardial digoxin levels were studied in 18 patients who came to autopsy. An
independent analysis of electrocardiograms prior to death was made to ascertain the …

A radioimmunoassay for serum digoxin concentration has been used to study the
interrelationships of circulating levels of the drug and various factors in the clinical setting in …

The measurement of digoxin in plasma or serum using the technique of radioimmunoassay
is both rapid and reliable, and a relationship between the electro-cardiographic signs …

Forty-seven patients who were being treated with digoxin in a daily dose range of 0.25 mg.
to 0.75 mg. were the study material. Thirty-two patients were toxic. Seven patients out of …

Methods During the period of July, 1971, to June, 1973, the serum digoxin concentration
was determined in Over 1,200 patients admitted to the University of Kansas Medical Center …

Results Of the io8 subjects studied, 54 were men and 54 were women; 22 (20'4%) were
found to have clinical or electrocardiographic evidence of digoxin toxicity. The results are …

Using the radioimmunoassay technique for measuring serum digoxin, it was found that
patients who were given 0.25 mg. digoxin orally per day had a mean serum level of …

Abstract A sensitive (0.2 ng per milliliter), precise (standard deviation 3 to 4 per cent), and
specific radioimmunoassay for serum digoxin concentration has been developed. Levels are …
