acetylstrophanthidin/심방세동

The response of the AV junction to adrenergic stimulation was studied in 35 anesthetized open-chest dogs before and after the injection of acetylstrophanthidin (5mug) directly into the AV node artery. An AV junctional rhythm was obtained under control conditions by injecting norepinephrine (n = 9)

BACKGROUND Despite a long history of use in the treatment of paroxysmal atrial fibrillation (AF), the efficacy of cardiac glycosides has not been established. If such drugs are beneficial in this condition, the general view is that the benefit must be related to their inotropic actions. RESULTS To

The present investigation was designed to study the relationship between mechanical and electrophysiological actions on the heart of digitalis and the effects on it of K administration. Nineteen anesthetized dogs were given acetylstrophanthidin (AS) (30 gamma/Kg, followed by 1 gamma/Kg/min. When
