2. Catheter ablation - Wikipedia

   en.wikipedia.org/wiki/Catheter_ablation

   D017115. [edit on Wikidata] 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

   Schematic view of a pulmonary vein ablation. The catheter reaches (from below) through the inferior vena cava, the right atrium and the left atrium, to the orifice of the left upper pulmonary vein. Radiofrequency energy is used in heart tissue or normal parts to destroy abnormal electrical pathways that are contributing to a cardiac arrhythmia.

4. Atrial fibrillation - Wikipedia

   en.wikipedia.org/wiki/Atrial_fibrillation

   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 ]

5. Atrial flutter - Wikipedia

   en.wikipedia.org/wiki/Atrial_flutter

   Atypical atrial flutter rarely occurs in people who have not undergone previous heart surgery or previous catheter ablation procedures. Left atrial flutter is considered atypical and is common after incomplete left atrial ablation procedures. [13] Atypical atrial flutter originating from the right atrium and heart's septum have also been described.

6. Management of atrial fibrillation - Wikipedia

   en.wikipedia.org/wiki/Management_of_atrial...

   The management of atrial fibrillation (AF) is focused on preventing temporary circulatory instability, stroke and other ischemic events. Control of heart rate and rhythm are principally used to achieve the former, while anticoagulation may be employed to decrease the risk of stroke. [ 1] Within the context of stroke, the discipline may be ...

7. Left atrial enlargement - Wikipedia

   en.wikipedia.org/wiki/Left_atrial_enlargement

   Left atrial enlargement can be mild, moderate or severe depending on the extent of the underlying condition. Although other factors may contribute, left atrium size has been found to be a predictor of mortality due to both cardiovascular issues as well as all-cause mortality. Research suggests that left atrium size as measured by an echo ...
