Atrial Flutter vs. Atrial Fibrillation !
There are many similarities between atrial fibrillation and atrial flutter, there are also significant differences.Atrial flutter is an abnormality of conduction within the atria and, as with AF, the ventricles work normally.The causes and symptoms are also very similar to AF, as is the treatment, although the symptoms tend to be less severe and there is less risk of embolisation (clot formation). Atrial Flutter also tends to revert back to sinus rhythm spontaneously in some cases.
Unlike AF, atrial flutter emanates from a small group of ectopics, or a single ectopic focus within the atria. The sequence of electrical impulses tends to be more regular than in AF. The AV node, (as in AF), still acts as a “gatekeeper” and only conducts every second or third impulse due to the refractory period.
