Most patients with atrial flutter should be considered for long-term anticoagulation in a manner similar to those with atrial fibrillation (AF). On entend sous le terme général de FA: la fibrillation auriculaire et, par extension, le flutter auriculaire et la tachycardie atriale. Dans le cadre de ce guide, sont. notation. prefLabel.

Atrial flutter (AFL) (video) | Khan Academy

Lesional tachycardias related to mitral valve surgery. Multifocal atrial tachycardia MAT.

If high embolic risk is present, anticoagulation should be continued indefinitely, unless prolonged follow-up monitoring demonstrates an absence of recurrence. Heart Rhythm ; 6: Atrial fibrillation after radiofrequency ablation of type I atrial flutter: The superior transseptal surgical approach to mitral valve creates slow conduction.

Long-term use of blood thinners e. Risk of thromboembolism in chronic atrial flutter. Prednisone prevents inducible atrial flutter in the canine sterile pericarditis model. Thus, any thrombus material that dislodges from this side of the heart can embolize break off and travel to the brain’s arteries, with the potentially devastating consequence of a stroke. In these cases, a device capable of overdrive atrial pacing should be auticulaire.

In doubtful cases it is essential to document atrial activity dissociated from ventricular activity by increasing AV block by vagal manoeuvres or intravenous adenosine. Retrieved from ” https: Transoesophageal atrial pacing is safe and effective for conversion. Characterization of low right atrial isthmus as the slow conduction zone and pharmacological target in typical atrial flutter. Radiofrequency ablation of atrial flutter: Heart Rhythm ; 7: Views Read Edit View history.


After the AV node conducts the signal, to the lower half of the heart, there’s a window of time also known as the refractory period where the AV node can’t fire again even if it gets the signal to do so.

Atrial Flutter, Typical and Atypical: A Review

Early studies suggested that flutter had a re-entrant mechanism 3—5 but others attributed flutter to focal discharge. Management of atypical flutter does not differ from that of typical flutter, but the more frequent association with structural heart disease and the multiple possible mechanisms causing an atypical ECG pattern are important factors to consider before making therapeutic decisions.

Chronic anticoagulation should be considered on the bases of embolic and haemorrhagic risk scores, along the same lines as for AF. Now why is that? Can augiculaire current isthmus ablation damage the right coronary artery? A first and well-tolerated episode of flutter terminated spontaneously or by electrical cardioversion or AAD can be followed clinically with or without AAD coverage.

Aggressive risk factor reduction study for atrial fibrillation and implications for the outcome of ablation: So let’s look at this auriculairr EKG. His development and clinical examination were normal two months later.

Atrial flutter

Accelerated idioventricular rhythm Catecholaminergic polymorphic Torsades de pointes. Atrial flutter mapping and ablation II. So for example here, we have the focus firing, causing the atria to contract, it hits AV node, conducts, makes QRS complex and it tries to fire again but because we’re in the refractory period it’s not going to conduct through the AV node and you’re not going to get another QRS complex.


Differential pacing for distinguishing block from persistent conduction through an ablation line. To log in and use all the features of Khan Academy, please enable JavaScript in your browser. The poor results of rhythm control strategies in AF may not apply in flutter because of a lower recurrence rate after cardioversion in flutter, making a strategy of repeated cardioversions supported with AADs a clinically applicable option.

There is paucity of published data directly comparing the two, but overall mortality in these conditions appears to be very similar. Heart Rhythm ; Right atrial remodeling is more advanced in patients with atrial flutter than with atrial fibrillation. EP studies with RA and LA activation mapping and the response to pacing are necessary to reveal the mechanism in order to guide catheter or surgical ablation.

Prediction of uneventful cardioversion and maintenance of sinus rhythm from direct-current electrical cardioversion of chronic atrial fibrillation and flutter. A blood clot in the left atrial appendage is particularly important as the auriculaite side of the heart supplies blood to the entire body through the arteries. J Cardiovasc Electrophysiol ;
