In atrial fibrillation, a problem with the heart's electrical system causes the two upper chambers of the heart (called the atria) to quiver, or fibrillate. Atrial fibrillation can be dangerous. This is because if the heartbeat isn't strong and steady, blood can collect, or pool, in the atria.Dec 19, 2015 · Major unmet needs in managing patients with atrial fibrillation (AF) are to track AF propensity, monitor therapeutic response, and ultimately predict AF episodes. We are disappointingly far from these goals because our basic tools in AF—atrial electrograms and their classic interpretation—provide limited actionable data on substrates, their progression, AF initiation, or critical sites ...
Overview. Atrial fibrillation ablation is a treatment for an irregular and often very fast heartbeat called atrial fibrillation (AFib). The treatment uses heat or cold energy to create tiny scars in an area of the heart. The signals that tell the heart to beat can't pass through scar tissue.A total of 18 studies examining atrial fibrillation detection, bradyarrhythmias and tachyarrhythmias, and premature contractions were analyzed, measuring diagnostic accuracy in 424,371 subjects in total. ...

The problem prevents blood from flowing normally to the ventricles (the two bottom cardiac chambers).Take Home Messages. Every additional standard alcoholic drink per day increases the risk of incident atrial fibrillation (AF) by 8%. Abstinence from alcohol among regular drinkers may reduce the risk of recurrence of AF and AF burden. Whether similar benefits can be derived from a mere reduction in alcohol consumption remains to be proven.
Atrial fibrillation can be interpreted by noting: PR intervals that vary from complex to complex. an irregularly irregular rhythm and absent P waves. the presence of wide QRS complexes and a rapid rate. a regularly irregular rhythm with abnormal P waves.
Other irregular rhythms may resemble atrial fibrillation on ECG but can be distinguished by the presence of discrete P or flutter waves, which can sometimes be made more visible with vagal maneuvers. Muscle tremor or electrical interference may resemble f waves, but the underlying rhythm is regular. Atrial fibrillation may also cause a phenomenon that …
