	Atrial flutter - Wikipedia, the free encyclopedia
		Atrial flutter is a rhythmic, fast rhythm that occurs in the atria of the heart.
		Atrial flutter is typically not a stable rhythm, and frequently degenerates to atrial fibrillation.
		While entrainment may break atrial flutter and cause the individual to revert to a normal sinus rhythm, the rapid atrial pacing may cause the individual to go into atrial fibrillation.

	atrial flutter (Site not responding. Last check: 2007-11-07)
		Atrial flutter is a very rapid, regular heart beat that starts in the atria, or upper chambers of the heart.
		In a person with atrial flutter, the regular beating of the atria is replaced by a rapid beating, known as atrial flutter.
		Atrial flutter is caused by a short circuit in one atrium.

	U-M CVC - Atrial Flutter (Site not responding. Last check: 2007-11-07)
		Atrial flutter is an abnormal, rapid heart rhythm that comes from the heart’s upper chambers — the atria — causing them to beat at rates of 220 to 300 times a minute.
		Atrial flutter is uncommon in the young except when there is a history of heart surgery involving the atria.
		Atrial flutter occurs when an electrical impulse travels in a circle around the atria like "a dog chasing its own tail." This happens when there are areas of slow and fast conduction in the atria, which is quite common after having surgery in this area.

		In atrial fibrillation and flutter, the atria are stimulated to contract very quickly and differently from the normal activity originating from the sinoatrial node.
		For most patients with atrial flutter, radiofrequency ablation is the current treatment of choice.
		Some patients with atrial fibrillation and rapid heart rates may need the radiofrequency ablation done not on the atria, but directly on the AV junction (i.e., the area that normally filters the impulses coming from the atria before they proceed to the ventricles).

	Atrial Flutter
		The most common form of atrial flutter is attributable to a large reentrant loop confined to the right atrium that travels in a counterclockwise direction, caudiocrandially in the interatrial sptum and craniocaudally in the right free atrial wall.
		This common form of atrial flutter is characterized electrocardiographically by sawtoothed flutter waves that are negative in leads 11, 111, and aVF and show continual electrical activity (lack of an isoelectric interval between flutter waves, see figure 5a).
		In this type of atrial flutter, an area of slow conduction is present in the posterolateral to posteromedial inferior right atrium between the tricuspid valve annulus and the inferior vena cava orifice (figure 11f).

	Atrial fibrillation and flutter
		Atrial fibrillation and flutter are abnormal heart rhythms in which the atria, or upper chambers of the heart, are out of sync with the ventricles, or lower chambers of the heart.
		Atrial flutter is less common, but both of these arrhythmias can cause a blood clot to form in the heart.
		Patients with atrial fibrillation and flutter can live a normal life for many years as long as the arrhythmia is controlled and serious blood clots are prevented.

	eMedicine - Atrial Flutter : Article by Lawrence Rosenthal, MD, PhD
		Type II atrial flutter is associated with atrial rates from 340-433 bpm and is not as well characterized electrically as type I. Type I atrial flutter can always be electrically entrained and interrupted by atrial pacing at faster rates than the intrinsic rate of the tachycardia, whereas type II atrial flutter cannot be electrically entrained.
		For typical atrial flutter, pacing from the tricuspid valve isthmus during atrial flutter causes concealed entrainment such that the morphology of the paced flutter waves is identical to that of the native flutter waves.
		Patients with atrial flutter and episodes of atrial fibrillation are at higher risk of thromboembolic events; however, determining whether episodes of atrial fibrillation are associated with episodes of atrial flutter is difficult.
