2. Atrial fibrillation - Wikipedia

   en.wikipedia.org/wiki/Atrial_fibrillation

   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 ]

3. Supraventricular tachycardia - Wikipedia

   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 ...

   What triggers Afib? Afib happens when those cells start acting up after being triggered by something. That something could develop over time, fed by poor diet and exercise or a lifetime of ...

5. Atrial flutter - Wikipedia

   en.wikipedia.org/wiki/Atrial_flutter

   However, atrial flutter is more resistant to correction with such medications than atrial fibrillation. [1] For example, although the class III antiarrhythmic agent ibutilide is an effective treatment for atrial flutter, rates of recurrence after treatment are quite high (70–90%). [1]

6. Atrial tachycardia - Wikipedia

   en.wikipedia.org/wiki/Atrial_tachycardia

   Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.

7. Fibrillation - Wikipedia

   en.wikipedia.org/wiki/Fibrillation

   There are two major classes of cardiac fibrillation: atrial fibrillation and ventricular fibrillation. Atrial fibrillation is an irregular and uncoordinated contraction of the cardiac muscle of atria. It can be a chronic condition, usually treated with anticoagulation and sometimes with conversion to normal sinus rhythm.
