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 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.

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 ...

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%).

The Management of Atrial Flutter
2002Atrial flutter was first described in 1911 by Jolly and Ritchie (1), who differentiated this arrhythmia from atrial fibrillation (AF) and reported the typical saw-tooth-shaped atrial waves in leads II and III. Early insight into atrial flutter was facilitated by Lewis, who defined the electrocardiographic findings and through a series of animal ...

Pacing and Clinical Electrophysiology, 1983
In patients with Wolff‐Parkinson‐White syndrome (WPW), it is important to assess the ventricular response during atrial flutter or fibrillation since conduction across the accessory pathway during these atrial rhythms may cause hemodynamic impairment or life‐threatening ventricular arrhythmias.

Atrial Tachycardias and Atrial Flutter
2000Atrial tachyarrhythmias are defined as supraventricular tachyarrhythmias that do not require the AV node or ventricular tissue for initiation and maintenance. Therefore, this definition excludes AV junctional tachycardia, AV nodal reentrant tachycardia, and AV reciprocating tachycardia involving an accessory AV connection.
