The isthmus dependent atrial flutter is divided into two forms: a) Common anticlockwise flutter (AFL type 1) and b) Uncommon clockwise flutter (AFL type 2) (Figure 1). The right atrial flutter is, in turn, divided into two subgroups, right atrial flutter isthmus dependent (typical) and right atrial flutter non isthmus dependent (atypical). Scheinman, the atrial flutter is distinguished according to the chamber in which it originates, in right atrial flutter and left atrial flutter. Since the atrioventricular node is unable to conduct at this speed, the impulses are conducted to the ventricles according to a conduction ratio that can be fixed, giving a regular ventricular rhythm (for example in the case of 2:1 conduction, with FC 150 bpm) or variable from moment to moment, according to variable conduction ratios (3:1, 4:1, or 5:1), giving a regular and sometimes irregular ventricular rhythm.Īccording to the classification sec. In the case of atrial flutter, the atria depolarize at a rate of 250-350 beats/min. The diagnosis of AFL is based on the 12-lead ECG or on the ECG according to Holter, which highlights the atrial activation with the typical sawtooth pattern (called F waves). What are the electrocardiographic features of atrial flutter? Transcatheter radiofrequency ablation is the therapy of choice for the treatment of atrial flutter. The atrial flutter is due to a re-entry macrocircuit, generally located in the right atrium, and is not very sensitive to antiarrhythmic drugs commonly used for atrial fibrillation (class I and III). As in atrial fibrillation, atrial thrombi can form, which can then embolize. AFL symptoms include palpitations, exercise intolerance, dyspnoea and presyncope. What are the treatments for atrial flutter?Ītrial flutter is a relatively frequent form of atrial arrhythmia that often occurs in association with atrial fibrillation and can cause important adverse events, such as cardioembolic stroke, myocardial ischemia and sometimes tachycardiomyopathy, due to rapid atrioventricular conduction.What are the electrocardiographic features of atrial flutter?.Master in Physiology and pathology of ion channels in cardiovascular diseases – full video.Master in Physiology and pathology of ion channels in cardiovascular diseases – eng.Master in Electrocardiography – full video.Master in Basic Electrocardiography – eng.MD Program 2020-2021- Cardiology Course.MD Program 2021-2022 – Cardiology Course.The Institute of Molecular and Translational Cardiology (IMTC).Genetic Syndromes with Cardiovascular Involvement.Connective Tissue Disorders (Marfan Syndrome and Ehlers Danlos Syndrome).Coagulation Disorders (Deficiency in Factor VIII, Factor IX, Factor X, Thrombotic Diathesis).Atrioventricular Nodal Reentrant Tachycardia (AVNRT).Wolff-Parkinson White Syndrome (WPW): Atrio-ventricular Reentry Tachycardia.Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia (ARVC/D).How to access our Cardiogenetic Service.Scientific collaborations of the Cardiogenetic Service.Frequently asked questions about cardiogenetics.Our experience in genetic heart disease.Informed Consent Arrhythmological Procedures and Therapies.Medication cards Intensive care (urgency).Informative NAO Dosages in Chronic Kidney Failure.Information for NAO Suspension for Surgery Interventions.Occlusione Percutanea dell’Auricola-eng.Information of the Manufacturing Companies.Information for Patients with Implantable Devices.Resynchronizer System (CRT-D and CRT-P).Implantable Subcutaneous Defibrillators (S-ICD).Implantable Cardioverter Defibrillator (ICD).Anesthetic Management of Electrophysiological Procedures.Ablation and Modulation of the Atrio-Ventricular Node.Ventricular Extrasystoles Ablation (PVC).Atrioventricular Nodal Reentrant Tachycardia (AVNRT) Ablation.Atrio-Ventricular Abnormalities (WPW) Ablation.Arrythmological Procedures and Therapies.Informed Consent Visits and Outpatient Diagnostics.Information for remote monitoring of implantable devices.Echocardiography with Provocative Testing.Casa di Cura la Madonnina – Via Quadronno, 29 – Milano.Università Vita e Salute San Raffele Milano.
