Ablation flutter8/3/2023 The atypical atrial flutter is independent of the CTI, and the origin of the arrhythmia can be in the right atrium or the left atrium. Typical atrial flutter is seen in the electrocardiogram as continuous negative modulation in inferior leads (II, III, and AVF) and flat atrial deflections in leads I and aVL this is due to the way of propagation and activation of the macro-reentrant circuit as will be described in the pathophysiology section. Typical or cavotricuspid isthmus (CTI) dependent is the most common type of atrial flutter this rhythm originates in the right atrium at the level of the tricuspid valve annulus. Electrical axis of the flutter waves can help to determine the origin of the atrial flutter. Electrocardiographic findings of atrial flutter are flutter waves without an isoelectric line in between QRS complex. Ītrial flutter is a macro-reentrant tachycardia and depending on the site of origin can be typical or atypical atrial flutter. In this review will summarize the management of atrial flutter.Ītrial flutter is one of the most common arrhythmias and is characterized by an abnormal cardiac rhythm that is fast with an atrial rate of 300beats/min and a ventricular rate that can be fixed or be variable that can cause palpitations, fatigue, syncope, and embolic phenomenon. Atrial fibrillation and atrial flutter are the most common of these atrial arrhythmias, and the other less common supraventricular arrhythmias are atrial tachycardias, atrioventricular reentrant tachycardia, atrioventricular nodal tachycardia, and others. Supraventricular arrhythmias are a diverse group of atrial arrhythmias.
