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.

Atrial flutter (AFl) is an arrhythmia resulting from reentry in a macroreentrant circuit, most commonly in the right atrium. Typical AFl uses the narrow isthmus of right atrial tissue between the tricuspid valve annulus and the inferior vena cava orifice as part of the macroreentrant circuit.

A 78-year-old woman presented with involuntary movements of her abdomen, which started after a right hemispheric stroke. She had irregular, variable, hyperkinetic predominantly right-sided abdominal wall movements. MR scan of brain confirmed a recent infarct in the right occipitotemporal lobe and the right cerebellum.

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

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.

Microsaccadic flutter is a rare symptomatic saccadic oscillation that has been reported only twice previously. Here we describe 5 patients with this disorder. The oscillation is horizontal, has a frequency of 15-30 Hz, an amplitude of 0.1-0.5 degrees, and cannot be seen with the unaided eye. It is usually not associated with any underlying neurological

MECHANISM OF FLUTTER AND FIBRILLATION
Archives of Internal Medicine, 1953THE PHENOMENON of cardiac fibrillation has been known for more than a century. Its discovery immediately aroused considerable interest, but for several decades before 1946 little attention was paid to the mechanism of this arrhythmia. There were several reasons for this.

The Concept of Stability and Types of Instability THE term stable or unstable is applied to a body or system in accordance with the nature of the ultimate consequence of applying a disturbance. If the body or system is at rest and in equilibrium in a certain configuration, that configuration is said to be completely stable if the system ultimately ...
