Abstract
The effects of oral digoxin and placebo in 41 geriatric in-patients were compared using a randomized, double-blind, cross-over method. The patients were in sinus rhythm or had atrial fibrillation. The observation period was 2 mo. on digoxin or placebo. Patients with symptoms of cardiac failure at rest or during light physical activity, X-ray signs of pulmonary congestion, proven need of digoxin therapy following earlier withdrawal, atrial fibrillation with a ventricular rate > 95 beats/min and patients in whom digitalis intoxication was suspected were excluded from the study. Five (14%) of 37 patients deteriorated during the placebo phase. Four of these developed rapid atrial fibrillation and 1 developed sinus tachycardia and symptoms of heart failure.
