Related to flutter: atrial flutter, flutter device

flutter

 [flut´er]
a rapid vibration or pulsation.
atrial flutter a cardiac arrhythmia in which the atrial contractions are rapid (230–380 per minute), but regular. Two types, I and II, are distinguished according to rate; Type I is also more amenable to cardioversion. In Type I the atrial rate is usually 290 to 310 per minute but can range from 230 to 350. In Type II the atrial rate is usually 360 to 380 per minute but can range from 340 to 430.
diaphragmatic flutter peculiar wavelike fibrillations of the diaphragm of unknown cause.
impure flutter atrial flutter in which the atrial rhythm is irregular.
mediastinal flutter see mediastinal flutter.
pure flutter atrial flutter in which the atrial rhythm is regular.
ventricular flutter a possible transition stage between ventricular tachycardia and ventricular fibrillation, the electrocardiogram showing rapid, uniform, and virtually regular oscillations, 250 or more per minute.

n.
Abnormally rapid pulsation, especially of the atria or ventricles of the heart.
A family of cardiac tachyarrhythmias characterised by rapid regular atrial (250-350/min) or ventricular (200/min) rhythms

flutter

Cardiology A family of cardiac tachyarrhythmias characterized by rapid regular atrial–250-350/min or ventricular–200/min rhythms. See Atrial flutter, Ventricular flutter. Cf Fibrillation.
Flutter types
Atrial flutter occurs at 200-350 beats/min (with a 2:1 block, so that the ventricle fires at ± 150 beats/min); AF results from a circus pathway, occurs in atrial dilatation, primary myocardial disease, or rheumatic heart disease and responds poorly to antiarrhythmics
Ventricular flutter is characterized by a continuous and regular depolarization rate of greater than 200 beats/min, and demonstrates high-amplitude zigzag pattern on the EKG, without clear definition of the QRS and T waves, a pattern that may revert spontaneously to a normal sinus rhythm or progress to ventricular fibrillation

However Flutter, as the name suggested, was very light in look and feel and did not really resonate with regular punters, and it was swiftly overtaken by - and then eaten by - Betfair, who in effect took over their rival in December 2001.

The flutter designates the non-damped oscillations of some construction parts under the action of aerodynamic forces that are generated during oscillations.
During the writing process for Wow and Flutter, Spicer took time to work on several other projects.

According to previous researches [1, 3], an assumption of small-amplitude vibration around nonlinear static equilibrium state is suitable for aeroelastic stability problem such as flutter analysis.
Starting with this goal, this paper proposes the novel and new flutter stability of the bridge section model based on the simulated annealing algorithm (Soni, 2013; Wang, 2014).
Years ago, I was flying a friend's P-51 Mustang and was flying low-level at roughly 400 knots (at the time there was no speed restriction below 10,000 feet) when the rudder flutter began.
But you should also be aware of a similar condition, called atrial flutter. Like afib, atrial flutter is a problem with the hearts electrical system.
The company said the Blazer OI catheter is designed for use in ablation procedures to restore a normal heart rhythm for patients in atrial flutter. The localized electrical energy is delivered through an electrode on the tip of a catheter into the heart muscle, creating heat to destroy a small area of the tissue responsible for the abnormal heart rhythm.
