showing the identifying characteristics of atrial fibrillation: &nbsp;no P waves, an irregularly-irregular rhythm, and a "fibrillatory" baseline. &nbsp;The wavy baseline will not be seen in all leads in all patients, so it is best to use the first two findings as diagnostic criteria. &nbsp;Atrial fib often appears initially as a rapid rhythm, as the AV node is being bombarded by many impulses from multiple foci (pacemakers) in the atria. &nbsp;Depending upon the AV node's ability to transmit these impulses,however, we could see a slow, normal, or rapid ventricular response.&nbsp;</p><p>Atrial fib has very chaotic depolarization of the atrial muscle, resulting in quivering and ineffective pumping of the atria. &nbsp;This loss of "atrial kick" can severely reduce ventricular filling, and can reduce cardiac output by as much as 25%. &nbsp;In patients with a very rapid rate, cardiac output can be further reduced, causing CHF. &nbsp;In addition, the fibrillating atria can form blood clots due to sluggish movement of blood. &nbsp;These clots can embolize and cause stroke. &nbsp;For these reasons, patients with atrial fib are anticoagulated and sometimes the atrial fib is stopped by medical, surgical, or electrical therapy. &nbsp;Recurrence of atrial fib is common after treatment, and for some patients, control of the ventricular rate and anticoagulation become the preferred treatment.</p></div></div></div><div class="field field-name-field-rate-this-content field-type-fivestar field-label-above"><div class="field-label">Rate this content:&nbsp;</div><div
