Atrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the atrial ...

In this situation, giving adenosine will transiently slow the ventricular rate, unmasking the atrial flutter waves and allowing a more definitive diagnosis to be made. On physical examination ...

Additional categories were assigned for atrial fibrillation or atrial flutter and malignant ventricular arrhythmias (i.e. ventricular tachycardia, fibrillation or flutter). Analysis was by ...
