8/18/2023 0 Comments Afib vs a flutter![]() The ECG pattern shows regular mainly negative atrial deflections in the inferior leads with a 'saw-tooth pattern' at rates of 240-350 bpm per minute. This is also called cavotricuspid isthmus (CTI) or common atrial flutter. In typical atrial flutter the rhythm has its origin in the right atrium at the level of the tricuspid valve.Like atrial fibrillation, it can be paroxysmal or persistent. Atrial flutter is a macro-reentrant tachycardia and can be classed as typical or atypical atrial flutter depending upon the origin. There is typically an atrial rate of around 300 beats per minute (bpm) and a ventricular rate that may be fixed or be variable. ![]() Pathophysiology Ītrial flutter is characterised by an abnormal and rapid heart rhythm. See also the separate Atrial Fibrillation article. Both arrhythmias can cause clinical symptoms such as palpitations, syncope and fatigue, and are associated with a risk of thrombus formation and thromboembolism. European and American guidelines cover the conditions separately although there, much of the management is the same. There are many similarities in clinical presentation and management, and indeed the guideline from the National Institute for Health and Care Excellence (NICE) makes hardly a distinction, stating the guideline for atrial fibrillation applies to patients with atrial flutter, specifying a particular management in the latter only in one sentence. Many patients with atrial flutter have associated atrial fibrillation. Atrial flutter is one of the more common atrial arrhythmias (supraventricular arrhythmias).
