    Oftentimes, people with AF start with what are called paroxysmal events, which means AF suddenly comes and goes, lasting less than a week at a time, probably because the tissue is still relatively healthy. Repeated paroxysmal events that occur over longer periods of time, though, tend to stress the atrial cells even more.

    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]

    en.wikipedia.org/wiki/Supraventricular_tachycardia

    Atrial fibrillation: Red dots show atrial fibrillation activity. Atrial fibrillation meets the definition of SVT when associated with a ventricular response greater than 100 beats per minute. It is characterized as an "irregularly, irregular rhythm" both in its atrial and ventricular depolarizations and is distinguished by its fibrillatory ...

    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 ...

    en.wikipedia.org/wiki/Sinus_node_dysfunction

    Sinus node dysfunction can also present with sudden sinus arrest with or without junctional escape, sinoatrial block, prolonged asystolic period followed by tachycardias, or tachycardia-bradycardia syndrome presenting as various atrial arrhythmias such as atrial fibrillation, flutter, tachycardia, or paroxysmal supraventricular tachycardia. [7] [5]

    en.wikipedia.org/wiki/Paroxysmal_supra...

    Paroxysmal supraventricular tachycardia (PSVT) is a type of supraventricular tachycardia, named for its intermittent episodes of abrupt onset and termination. [3] [6] Often people have no symptoms. [1] Otherwise symptoms may include palpitations, feeling lightheaded, sweating, shortness of breath, and chest pain. [2] The cause is not known. [3]

  8. 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.

  9. Atrial Fibrillation Association - Wikipedia

    en.wikipedia.org/wiki/Atrial_Fibrillation...

    In 2011 an All-Party Parliamentary Group on atrial fibrillation (APGAF) was established in partnership with the AF Association. It is chaired by Glyn Davies MP, who is himself affected by AF. [10] The APGAF has published a number of reports on improving AF care in the NHS. [citation needed]
