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.

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 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.

On the Importance of Engine-Representative Models for Fan Flutter Predictions
Journal of turbomachinery, 2017Discrepancies between rig tests and numerical predictions of the flutter boundary for fan blades are usually attributed to the deficiency of computational fluid dynamics (CFD) models for resolving flow at off-design conditions.

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.

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.
