2. 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]

3. Ashman phenomenon - Wikipedia

   en.wikipedia.org/wiki/Ashman_phenomenon

   Ashman phenomenon, also known as Ashman beats, describes a particular type of wide QRS complex that is typically, but not always seen in atrial fibrillation.It is a type of cardiac aberrancy and it is more often misinterpreted as a premature ventricular complex.

4. 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 ...

5. First-degree atrioventricular block - Wikipedia

   en.wikipedia.org/wiki/First-degree_atrio...

   It was originally thought of as having a benign prognosis. In the Framingham Heart Study, however, the presence of a prolonged PR interval or first degree AV block doubled the risk of developing atrial fibrillation, tripled the risk of requiring an artificial pacemaker, and was associated with a small increase in mortality. This risk was ...

6. Tachycardia-induced cardiomyopathy - Wikipedia

   en.wikipedia.org/wiki/Tachycardia-induced_cardio...

   The types of SVT associated with TIC include atrial fibrillation, atrial flutter, incessant atrial tachycardia, permanent junctional reciprocating tachycardia, atrioventricular reciprocating tachycardia, and atrioventricular nodal reentry tachycardia. [1] Atrial fibrillation is the most common and well-studied etiology of TIC. [1] [5]

7. Arrhythmia - Wikipedia

   en.wikipedia.org/wiki/Arrhythmia

   Fibrillation can affect the atrium (atrial fibrillation) or the ventricle (ventricular fibrillation): ventricular fibrillation is imminently life-threatening. Atrial fibrillation affects the upper chambers of the heart, known as the atria. Atrial fibrillation may be due to serious underlying medical conditions and should be evaluated by a ...

8. Atrioventricular reentrant tachycardia - Wikipedia

   en.wikipedia.org/wiki/Atrioventricular_reentrant...

   Atrioventricular reentrant tachycardia (AVRT), or atrioventricular reciprocating tachycardia, is a type of heart arrhythmia with an abnormally fast rhythm (tachychardia); it is classified as a type of supraventricular tachycardia (SVT).

9. European Heart Rhythm Association score of atrial fibrillation

   en.wikipedia.org/wiki/European_Heart_Rhythm...

   The European Heart Rhythm Association score of atrial fibrillation (or EHRA score) is a classification system for the extent of atrial fibrillation.It places patients in one of four categories based on how much they are limited during physical activity; the limitations/symptoms are in regard to normal breathing and varying degrees in shortness of breath and/or angina.
