There is a sinister synergism between atrial fibrillation (AF) and heart failure (HF). A-fib is the most common heart rhythm abnormality. However, atrial fibrillation typically returns in many patients. Without a definitive trial, it is unknown whether intensive monitoring would increase atrial fibrillation detection and treatment rates more than standard monitoring and follow-up.
Atrial fibrillation has been associated with hyperthyroidism, acute alcohol intoxication, changes in the autonomic nervous system and is common after cardiac surgery. However, ablations may also be used to help patients with other, more complex arrhythmias, such as ventricular tachycardia and atrial fibrillation.
A technique for measurement of the extent of spatial organization of atrial activation during atrial fibrillation in the intact human heart. Any therapy that is used for atrial fibrillation has potential risks and must be prescribed on an individualized basis.
We uniquely examined the prospective association between the burden of atrial fibrillation using a noninvasive, short-term continuous monitoring approach and the subsequent risk of thromboembolism in paroxysmal atrial fibrillation. Sometimes a doctor may choose to use electrical cardioversion first if AF is of short duration (onset within 48 hours) and the transesophageal echocardiography shows no blood clots in the atria.
When the atria (upper chambers of the heart) are not pumping efficiently, as in atrial fibrillation, there is a risk of blood clots forming. Accordingly, this procedure is often reserved for the best candidates—younger patients with drug-resistant AF who have no significant structural heart disease.
The absent atrial contractions predispose to thrombus formation; annual risk of cerebrovascular embolic events is about 7%. Risk of stroke is higher in older patients and in patients with a rheumatic valvular disorder, hyperthyroidism, hypertension, diabetes, left ventricular systolic dysfunction, or previous thromboembolic events.
About 15 percent of all people who have strokes also have AFib. These include medical and procedural approaches to treating atrial fibrillation, atrial flutter and related heart abnormalities. At the AV node and beyond into the ventricles, the electrical impulse signals the ventricles to contract, and blood is pumped out of the ventricles to the body.
7 Yet, little is known about whether the burden of atrial fibrillation (ie, the amount of time spent in atrial fibrillation) independently increases the risk of stroke among patients with paroxysmal atrial fibrillation for whom decision making about stroke prevention strategies can be challenging.
A comparison of rate control and rhythm control in patients with recurrent persistent atrial fibrillation. If atrial fibrillation is long-standing and does not respond to other treatment, radiofrequency ablation of the AV node along with placement of a pacemaker may be done.

Surgical treatment of AF is rarely necessary because medications achieve satisfactory control in most cases. Our atrial fibrillation program participates in an afib medications database, tracking outcomes that helps us in further clarifying the best treatment options for our patients.
