315,000 with atrial flutter (2019) [ 10] Atrial fibrillation ( AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [ 11][ 12] It often begins as short periods of abnormal beating, which become longer or continuous over time. [ 4]
Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
Efficacy and risks of catheter ablation of AF are areas of active debate. A worldwide survey of the outcomes of 8745 ablation procedures [63] demonstrated a 52% success rate (ranging from 14.5% to 76.5% among centers), with an additional 23.9% of patients becoming asymptomatic with addition of an antiarrhythmic medication. In 27.3% of patients ...
Radiofrequency-based ablation for atrial fibrillation appears more effective than previously shown in clinical trials. Using real-world data, a new study found that the procedure eliminated atrial ...
ICD-9-CM. 37.33. [ edit on Wikidata] The Cox maze procedure, also known as maze procedure, is a type of heart surgery for atrial fibrillation . "Maze" refers to the series of incisions arranged in a maze -like pattern in the atria. Today, various methods of minimally invasive maze procedures, collectively named minimaze procedures, are used.
Radiofrequency ablation ( RFA ), also called fulguration, [ 1] is a medical procedure in which part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz). [ 2] RFA is generally conducted in the outpatient ...
0.2% [ 1] Wolff–Parkinson–White syndrome ( WPWS) is a disorder due to a specific type of problem with the electrical system of the heart involving an accessory pathway able to conduct electrical current between the atria and the ventricles, thus bypassing the atrioventricular node. [ 2][ 3] About 60% of people with the electrical problem ...
Inappropriate sinus tachycardia (IST) is defined as sinus tachycardia that is not caused by identifiable medical ailments, a physiological reaction, or pharmaceuticals (a diagnosis of exclusion) and is accompanied by symptoms, frequently invalidating and affecting quality of life. [ 2] IST symptoms include palpitations, chest discomfort ...
