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.

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.

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.

Roof‐dependent atrial flutter with an epicardial component: Role of the septopulmonary bundle
Cardiovascular Electrophysiology, 2019Catheter ablation of atrial fibrillation may predispose patients to the development of atypical atrial flutters (AFL). We describe two cases of roof dependent AFLs that failed to terminate despite posterior wall isolation.

Atrial flutter is a supraventricular tachydysrhythmia believed to arise from electrophysiologic disturbances in the atria. It tends to be an unstable rhythm and is usually associated with intrinsic cardiac or pulmonary disease or adverse extrinsic influences on the heart.

The Journal of Pediatrics, 1969
Atrial flutter and atrial fibrillation present difficult problems in management, particularly during infancy. The clinical experience with 6 personally observed and 30 reported cases of infantile atrial flutter is described. Two types of flutter are distinguished: type I (congenital), which occurs prior to birth or within the first week of life ...

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.

Invasive electrophysiologic studies have changed the clinical outlook for patients with atrial flutter. Recognition of the reentrant circuit responsible for typical atrial flutter has led to the development of catheter ablation techniques that can prevent recurrence in >90% of cases. In addition, general understanding of atrial tachycardias has changed

Mapping and ablation of post-atrial fibrillation (AF) atrial tachycardia (AT) are challenging electrophysiologic procedures. These tachycardias may be caused by multiple mechanisms and may arise from the left or right atrium, or the coronary sinus. The precise mechanism must be defined before ablation because the procedural end point depends on the ...

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 ...
