Atrial fibrillation (AF) is a condition in which the upper chambers of the heart (atria) beat in a very rapid and irregular manner causing the lower chambers (ventricles) to also beat quickly and irregularly. It can be related to high blood pressure, previous heart attacks, heart valve disease or other heart disease, but in many patients no obvious cause can be found.
Pulmonary vein ablation, information for patients
Atrial fibrillation (AF) is a heart rhythm disorder with rapid, irregular, and chaotic electrical activity in the atria. The atrial electrical signals bombard the AV node, and some pass through the AV node to the ventricles, producing a rapid, irregular rate and often causing symptoms of palpi- tations, shortness of breath, or fatigue. AF affects more than 2 million people in the United States alone; it is seen progressively more frequently as a person ages.
Current Canadian guidelines for the management of atrial fibrillation
We recommend that all patients with AF or AFL (paroxysmal, persistent or permanent), should be stratified using a predictive index for stroke (e.g. CHADS2) and for the risk of bleeding (e.g. HAS-BLED), and that most patients should receive antithrombotic therapy.
