Atrial fibrillation and RF-based ablation. AFib is the most common form of arrhythmia — an abnormal heartbeat. In Australia, the United States, and Europe, it affects 1–4% of people and is ...
Catheter ablation of most arrhythmias has a high success rate. Success rates for WPW syndrome have been as high as 95% [ 2 ] For Supraventricular tachycardia (SVT), single procedure success is 91% to 96% (95% Confidence Interval) and multiple procedure success is 92% to 97% (95% Confidence Interval). [ 3 ]
[24] [27] Eliminating rotors increases success rates, even in patients with whom traditional techniques are less successful because of pre-existing conditions such as persistent atrial fibrillation, obstructive sleep apnea, metabolic syndrome, or body mass index.
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 ]
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
For TIC due to atrial fibrillation, rate control, rhythm control, and RF catheter ablation can be effective to control the tachyarrhythmia and improve left ventricular systolic function. [ 5 ] [ 9 ] For TIC due to atrial flutter, rate control is often difficult to achieve, and RF catheter ablation has a relatively high success rate with a low ...
