Changes in cardiac glycoside receptor sites, 86rubidium uptake and intracellular sodium concentrations in the erythrocytes of patients receiving digoxin during the early phases of treatment of cardiac failure in regular rhythm and of atrial fibrillation.
1 Measurements of the binding of 12-alpha-[3H]-digoxin to the membranes of intact erythrocytes, erythrocytic 86rubidium uptake and intraerythrocytic sodium concentrations have been made in the red cells of patients receiving digoxin in the short-term for atrial fibrillation or cardiac failure in regular rhythm. 2 During the first few days of treatment [3H]-digoxin binding and 86rubidium uptake fall and intraerythrocytic sodium concentrations rise. 3 Subsequently parallel fluctuations occur in...Expand abstract
