  2. Atrial fibrillation - Wikipedia

    en.wikipedia.org/wiki/AF_ablation

    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]

    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.

    Hypertension, atrial fibrillation and smoking pose a stronger risk for severe stroke, according to a new study. However, lifestyle changes can help prevent stroke.

  5. Pulsed field ablation - Wikipedia

    en.wikipedia.org/wiki/Pulsed_field_ablation

    Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [4] Pulmonary vein isolation ablation technology has used thermal methods (radiofrequency ablation or, less often, cryoablation) to destroy pulmonary vein cells. [5]

  6. Left atrial appendage occlusion - Wikipedia

    en.wikipedia.org/wiki/Left_atrial_appendage...

    The left atrial appendage is a pouch-like structure located in the upper part of the left atrium. [1] Left atrial appendage occlusion (LAAO) is an alternative therapy to oral anticoagulation in a certain subset of patients with atrial fibrillation. Atrial fibrillation is characterized by an irregular and uncoordinated pumping function of the atria.

  7. 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).
