title: Transient cardiac arrhythmias after single daily maintenance doses of digoxin.
abstract: Ten digitalized patients were monitored for detection of cardiac arrhythmias 0 to 8 hr after daily maintenance dose of digoxin in the fasting state. Transient cardiac arrhythmias attributable to digoxin were seen at 2 to 5 hr in 5 subjects. Initial serum concentrations of digoxin were within standard clinical limits in all subjects, but, higher steady-state levels were present in patients with arrhythmias (1.2 to 1.7 ng/ml) than in the others (0.7 to 1.2 ng/ml). The postadministrative serum peak concentrations were also higher in the patients with arrhythmias.
