Atrial flutter (AFL) is a common abnormal heart rhythm that starts in the atrial chambers of the heart. [1] When it first occurs, it is usually associated with a fast heart rate and is classified as a type of supraventricular tachycardia (SVT). [2]
In addition, atrial tachycardia can sometimes be terminated with adenosine. [7] Fast rhythms of the heart that are confined to the atria (e.g., atrial fibrillation and atrial flutter) or ventricles (e.g., monomorphic ventricular tachycardia), and do not involve the AV node as part of the re-entrant circuit, are not typically converted by ...
Treat atrial flutter and atrial fibrillation ... Adenosine is used to treat supraventricular tachycardias, especially in heart failure and atrial fibrillation [9]
Some atrial tachycardias, rather than being a result of increased automaticity may be a result of a micro-reentrant circuit (defined by some as less than 2 cm in longest diameter to distinguish it from macro-reentrant atrial flutter). Still other atrial tachycardias may be due to triggered activity caused by after-depolarizations. [19]
Synchronized electrical cardioversion is used to treat hemodynamically unstable supraventricular (or narrow complex) tachycardias, including atrial fibrillation and atrial flutter. It is also used in the emergent treatment of wide complex tachycardias, including ventricular tachycardia , when a pulse is present.
Atrial flutter is when the atria repeatedly contract at really high rates, usually due to an underlying condition combined with premature atrial contraction. Faster atrial contraction in turn increases the number of ventricular contraction, which can cause shortness of breath, chest pain, dizziness, and nausea in certain people.
All these ECG-based technologies also enable the distinction between AVNRT and other abnormal fast heart rhythms such as atrial fibrillation, atrial flutter, sinus tachycardia, ventricular tachycardia and tachyarrhythmias related to Wolff-Parkinson-White syndrome, all of which may have symptoms that are similar to AVNRT.
