Atrial FlutterAtrial Flutter is due to the fast irregular rhythm in the atria which mainly occurs when the electrical signals that control muscle contractions in the upper chambers (atria) of the heart become rapid sometimes causing the heart to beat at a rate greater than 300 beats per minute. It is a very fast beating of the atria (the upper two chambers of the heart). Atrial Flutter is a rhythmic, fast rhythm that occurs in the atria of the heart. This rhythm occurs most often in individuals with organic heart disease (ie: pericarditis, coronary artery disease, and cardiomyopathy). That is a rapid well-organized contraction of the atrium at a rate of 250-350 contractions per minute. Ventricular beats are usually some multiple of 300. ECG shows saw tooth waves. Atrial flutter is considered a serious and potentially unstable rhythm. This is a single "short circuit" in the atria that causes the atria to beat at about 300 beats per minute while the lower chambers of the heart (the ventricles) beat at a slower rate (often 75 or 150 beats per minute). A type of supraventricular tachycardia. Atrial flutter occurs when an abnormal conduction circuit develops inside the right atrium, allowing the atria to beat excessively fast, about 250-300 beats per minute. Atrial flutter commonly occurs in the setting of acute myocardial infarction, after pneumonectomy and after cardiac surgery in adults. It is unusual in children. Causes of Atrial FlutterSome common causes of Atrial flutter:
Signs and symptoms of Atrial flutterSigns and symptoms often experienced with atrial flutter are similar to those of atrial fibrillation, such as
Atrial flutter TreatmentAtrial fibrillation may require emergency treatment to convert the arrhythmia to normal (sinus) rhythm, either with electrical cardioversion or with the administration of intravenous drugs, such as dofetilide or ibutilide. For most patients with atrial flutter, radiofrequency ablation is the current treatment of choice. Atrial flutter commonly occurs in the setting of acute myocardial infarction, after pneumonectomy and after cardiac surgery in adults. It is unusual in children.
