With prolonged use, an overdose or hypersensitivity digitalis may cause toxic effects, early signs of which are sharp slowdown in heart rate (less than 60 beats per minute), a decrease in urine output in the presence of edema, rhythm disturbance of cardiac activity, the conductivity decrease (prolongation of the intervalPQ on an electrocardiogram).
First aid amounts to the abolition of digitalis preparations and the appointment of potassium salts (potassium chloride or acetate), atropine and camphor, as well as the use of warm baths.
the appointment of digitalis drugs must be strict compliance with bed rest and medical observation.
