Understanding of typical flutter circuits led the way to the study of other forms of macroreentrant tachycardias of the atria, and to their treatment by catheter ablation. It has become evident that the ECG classification of atrial flutter and atrial tachycardia by a rate cutoff and the presence or absence of isoelectric baselines between atrial ...

The Journal of Emergency Medicine, 1988
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.

Flutter stabilization and heaving-branch flutter
Journal of Wind Engineering and Industrial Aerodynamics, 1999Abstract This paper aims to clarify the flutter mechanism for super-long span bridges. A series of wind tunnel tests are conducted against the fundamental girder sections, such as flat diamond section, twin rectangular cylinder and rectangular cylinder with vertical plates installed at the mid-chord points. The former two sections indicate relatively

Proceedings of the 7th ACM conference on Designing interactive systems, 2008
Large collections of photographs are commonplace, and many interfaces for viewing, sorting and organizing them have been proposed. This work describes the design and implementation of a "living photo frame" - designed not to navigate or browse collections but to create an enjoyable activity from a collection of images.

Atypical Flutter: Peri-Mitral Flutter
2020A 68-year-old man presents with atypical appearing atrial flutter following surgical atrial fibrillation ablation. The atrial flutter was confirmed to be peri-mitral flutter, and endocardial ablation could not successfully eliminate atrial flutter, requiring ablation within the coronary sinus to terminate the tachycardia.

Flutter and Stall Flutter of a Rectangular Wing in a Wind Tunnel
AIAA Journal, 2011The aeroelastic behavior of a rectangular wing with pitch and plunge degrees of freedom was observed experimentally using pressure, acceleration, and particle image velocimetry measurements. The wing was set at different static angles of attack and wind-tunnel airspeeds. The wing’s dynamic behavior was governed by a twoparameter bifurcation from steady

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 ...

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.
