  2. Catheter ablation - Wikipedia

    en.wikipedia.org/wiki/Catheter_ablation

    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.

  3. Radiofrequency ablation - Wikipedia

    en.wikipedia.org/wiki/Radiofrequency_ablation

    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).

  4. Atrial fibrillation - Wikipedia

    en.wikipedia.org/wiki/Atrial_fibrillation

    Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]

    A catheter ablation is a minimally invasive procedure that stops the electrical impulses that cause irregular heart rhythms, according to the Mayo Clinic. A thin tube called a catheter is inserted ...

    These procedures are usually performed using intracardiac catheters (as are used during an electrophysiology study), fluoroscopy (a real-time X-ray camera), and electrical recordings from the inside of the heart. "Complex" ablations include ablation for arrhythmias such as multifocal atrial tachycardia, atrial fibrillation, and ventricular ...

    Finally, some patients may have a radiofrequency catheter ablation, where certain areas of tissue are destroyed such that the electrical signal doesn’t propagate any more. One type of procedure is the “maze procedure” where a maze of new pathways are created to help electrical impulses move in a more consistent and predictable pattern.
