Pseudoatrial Flutter Waves—When a Flutter Is Not a Flutter
JAMA Internal Medicine, 2016The patient’s medical history was significant for chronic obstructive lung disease, obstructive sleep apnea, type II diabetes mellitus, hypertension, hyperlipidemia, and major depressive disorder. The patient denied palpitations or light-headedness in the postoperative period.

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.

Assistive technology (AT) has the ability to improve the standard of living of those with disabilities, however, it can often be abandoned for aesthetic or stigmatizing reasons. Garment-based AT offers novel opportunities to address these issues as it can stay with the user to continuously monitor and convey relevant information, is non-invasive, and ...

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.

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.

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.

An analysis of unsteady airfoil stall and stall flutter is presented that is based on a series of approximations. Unsteady aerodynamic characteristics are related theoretically to static aerodynamic characteristics. Preliminary results show good agreement with experimental dynamic stall data.

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.
