Abstract. OVERVIEW: Atrial fibrillation, the most common chronic cardiac arrhythmia, adversely affects the quality of life of millions of people.The condition is frequently associated with advancing age, structural cardiac dysfunction, and preexisting comorbidities. The most common complications, stroke and heart failure, result in significant morbidity and mortality.

Nov 20, 2017  · Atrial flutter is a cardiac arrhythmia characterized by atrial rates of 240-400 beats/min, usually with some degree of atrioventricular (AV) node conduction block. In the most common form of atrial flutter (type I atrial flutter), electrocardiography (ECG) demonstrates a negative sawtooth pattern in leads II, III, and aVF.

Background The evidence for an association between alcohol consumption and risk of atrial fibrillation is conflicting. Methods We prospectively examined the association between alcohol consumption and risk of atrial fibrillation or flutter among 47 949 participants (mean age, 56 years) in the Danish Diet, Cancer, and Health Study. The consumption of alcohol was analyzed as sex-specific quintiles by Cox proportional.

Atrial flutter and atrial tachycardia are commonly observed arrhythmias. There are as many as 100,000 new cases of atrial flutter per year in the United States. The development of atrial flutter is associated with independent risk factors of heart failure and chronic obstructive pulmonary disease.

We conducted a multicenter trial to evaluate the use of dronedarone in 4628 patients with atrial fibrillation. Fibrillation/Atrial Flutter) are listed in the Supplementary Appendix, available with.

Atypical AFL with no previous cardiac intervention. In addition, atypical right atrial and septal flutters have been described in the literature. 1 , 2 The spectrum of atypical right atrial flutter has been described in an article by Yang et al. 1 These investigators observed atypical right atrial flutter in 8% of 372 patients presenting with AFL.

Sep 05, 2006  · Atrial Flutter in Infants Karen M. Texter, Naomi J. Kertesz, Richard A. Friedman, Arnold L. Fenrich, Jr We reviewed the natural history of atrial flutter (AFL) in 50 infants. The majority presented at one to 2 days of age with asymptomatic tachycardia. Ten presented in congestive heart failure, all with normalization of ventricular function after restoration of sinus rhythm.

The full-text articles were categorized into five groups: studies that provided estimates of the risk of thromboembolism around the time of therapeutic cardioversion; studies that provided estimates of the risk of thromboembolism over the longer-term; studies that only focused on echocardiographic findings associated with atrial flutter; case reports or case series of stroke/thromboembolism in patients with.

Atrial flutter is a macroreentrant tachyarrhythmia most often contained within the right atrium. Typical atrial flutter is defined on an electrocardiogram by the classic “sawtooth” pattern of flutter waves with negative polarity in leads II, III, and aVF.

Summary. An arrhythmia is a problem with the speed or rhythm of the heartbeat. Atrial fibrillation (AF) is the most common type of arrhythmia. The cause is a disorder in the heart’s electrical system. Often, people who have AF may not even feel symptoms. AF can lead to an increased risk of stroke.

Atrial fibrillation increases the risk for ischemic stroke and other arterial thromboembolism and affects millions of US adults. 1-3 Atrial fibrillation can lead to thrombus development within the atria, particularly the left atrial appendage, which can cause thromboembolic events. 4,5

Atrial flutter cycle length correlated to left atrial appendage emptying velocity. • Atrial flutter cycle length could be used to thromboembolic risk evaluation. • Cycle length, LA size and atypical AFL were predictors of low LAEV. • A new index may be able to identify higher occurrence of left atrial thrombus.

Heart diseases or problems that can cause atrial flutter include: Ischemia : Lower blood flow to the heart due to coronary heart disease, hardening of the arteries, or a blood clot. Hypertension : High blood pressure. Cardiomyopathy : Disease of the heart muscle.

Atrial flutter (AFL) is a common abnormal heart rhythm that starts in the atrial chambers of the heart. When it first occurs, it is usually associated with a fast heart rate and is classified as a type of supraventricular tachycardia. Atrial flutter is characterized by a sudden-onset (usually) regular abnormal heart rhythm on an electrocardiogram (ECG) in which the heart rate is fast.

Nov 15, 2009  · Supraventricular arrhythmias, a family of cardiac arrhythmias including supraventricular tachycardias and atrial flutter, are common, often persistent, and rarely life threatening. They arise from the sinus node, atrial tissue, or junctional sites between the atria and ventricles, and are amenable to medical and catheter-based therapies.

In atrial fibrillation, multiple atrial cells self-stimulate, behaving as individual pacemakers and competing with the sinoatrial node for control of cardiac activity. Normal atrial contractions are replaced by rapid quivering movements, and the atria stop contracting effectively.
