Linear correlation was demonstrated between serum digoxin and papillary muscle digoxin
concentrations in patients undergoing mitral valve surgery. The mean ratio of myocardial …

Digoxin concentration of 14 left ventricular papillary muscles and 36 right atrial appendages
of 45 patients undergoing cardiac surgery were determined by the NEN 125J …

In an attempt to evaluate the serum digoxin concentration as a guide to digitalis treatment,
serum and myocardial concentrations were measured in 27 patients undergoing cardiac …

Thirty-four dogs were given tritium-labeled digoxin intravenously. Serum and tissue
concentrations and half-times were determined. As demonstrated previously in human …

Plasma myocardial, and skeletal muscle digoxin concentrations were measured in 32
patients undergoing cardiopulmonary bypass who were on long-term treatment with digoxin …

Blood samples and skeletal muscle biopsies (m. quadriceps femoris, vastus lateralis) were
taken from seven healthy subjects for analysis of serum and skeletal muscle digoxin …

Biopsies of cardiac tissue were taken from patients undergoing surgery for coronary artery or
valvular disease. All subjects were on maintenance doses of digoxin, which were stopped …

Postmortal tissue digoxin concentration and prefinal and postmortal plasma digoxin
concentrations from 9 patients were determined using the 125J-digoxin radioimmunoassay …

Serum, right atrial myocardium and skeletal muscle collected from 32 adult patients
undergoing open heart surgery were analyzed for digoxin by radioimmunoassay …

After obtaining samples at open heart surgery, serum and right atrial digoxin concentrations
were measured in 25 children by a nonspecific, direct radioimmunoassay method (NS) and …
