Accelerated junctional rhythm causes

Vomiting is common in patients with digitalis overdose. Hyperkalemia may be caused by acute digitalis overdose or severe poisoning, whereas hypokalemia may be present in patients as a result of long-term diuretic treatment. (Digitalis does not cause hypokalemia.) A variety of cardiac rhythm disturbances may occur, including sinus bradycardia, AV block, atrial tachycardia with block, accelerated junctional rhythm, premature ventricular beats, bidirectional ventricular tachycardia, and other ventricular arrhythmias. 

Accelerated junctional rhythm and an accelerated Idioventricular rhythm appear similar but have different causes. To distinguish between them, closely examine the duration of the QRS complex, and then look for P waves. 

Treatment for accelerated junctional rhythm involves identifying and correcting the underlying cause.
