Atrial flutter (AFl) is an arrhythmia resulting from reentry in a macroreentrant circuit, most commonly in the right atrium. Typical AFl uses the narrow isthmus of right atrial tissue between the tricuspid valve annulus and the inferior vena cava orifice as part of the macroreentrant circuit.

Atrial Flutter. For five decades, the mechanism of atrial flutter remained controversial, with protagonists and antagonists of circus movement versus ectopic focus theories. The development of clinical electrophysiologv in the 1970s and the observations made by many authors in various canine heart models supported the concept of atrial flutter as a ...

Atrial flutter typically has a cycle length of 200 ms (300 cycles/min or 5 Hz); with 4:1 conduction through the AV node, this would lead to a ventricular rate of 75 bpm. We present a case of a patient with a Parkinsonian tremor at a frequency of 300 cycles/min that masqueraded as atrial flutter on the limb leads of a 12-lead ECG.

Pathophysiology of Atrial Flutter
Annual Review of Medicine, 1998Atrial flutter is a macroreentrant tachyarrhythmia most often contained within the right atrium. Typical atrial flutter is defined on an electrocardiogram by the classic “sawtooth” pattern of flutter waves with negative polarity in leads II, III, and aVF.

Cardiology in Review, 2001
Atrial flutter is a macroreentrant arrhythmia that is associated with cardiovascular and pulmonary disease. In the United States, 200,000 new cases of atrial flutter can be expected to develop every year with a male to female ratio of over 2:1. This arrhythmia is associated with atrial fibrillation in over half the cases.

Chest, 1975
Two cases of congenital atrial flutter, one of which was documented electrocardiographically before birth, are reported. In both patients sinus rhythm was restored with digoxin treatment; in one patient the transition was preceded by various arrhythmias. No cardiac malformation was found in either case, and no materal disease occurred during pregnancy.
