Cardiac Electrophysiology Review, 2002
Typical atrial flutter has long been considered a reentrant arrhythmia, but it is only recently that the full structure of the right atrial circuit was understood, leading to de devise of ablation techniques. Recognition of the role of functional block, based on anisotropic conduction was crucial to understanding of the flutter circuit.

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.

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 ...

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

Cardiac Electrophysiology Clinics, 2012
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 and Ventricular Pressures in Atrial Flutter
Pacing and Clinical Electrophysiology, 1999The hemodynamic effects of atrial flutter (AF) are unknown. The purpose of the present study was to investigate the changes in atrial and ventricular pressures after induction of AF. In 23 patients with paroxysmal AF (age 59 ± 9 years), a hemodynamic study was performed both during sinus rhythm and after induction of the tachyarrhythmia.

Atrial Fibrillation and Atrial Flutter
2020Atrial fibrillation (AF) is the most common sustained arrhythmia in the inpatient setting. It is often precipitated by physical stressors such as acute illness or surgery and can result in patient discomfort, hemodynamic instability, heart failure and thromboembolism.

Verapamil in atrial fibrillation and atrial flutter
Clinical Pharmacology & Therapeutics, 1979A double‐blind, randomized study was performed to compare the efficacy of intravenous verapamil with saline in 28 patients with a rapid ventricular rate and atrial fibrillation or atrial flutter. Conversion of atrial fibrillation to sinus rhythm occurred in none of 14 patients after saline and in 3 of 20 patients (15%) 7 to 160 min after verapamil. The

Atrial pacing for conversion of atrial flutter
The American Journal of Cardiology, 1986Fifty-seven episodes of atrial flutter in 46 consecutive medically treated patients (aged 60 +/- 17 years) were treated by rapid atrial pacing. Thirty-three patients (72%) had structural heart disease. Most pacing trials were conducted in patients receiving digoxin (88%) and antiarrhythmic drugs (77%).
