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.

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

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

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.

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 ...

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
