  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 ...

    Atrial fibrillation (afib or AF) – Fibrillation of the atria is fairly common and more common with increased age and overall disease of the heart. If the ventricular rate exceeds 100 then the afib is further classified as "afib with RVR" meaning rapid ventricular response.

    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 ...

  7. Rhythm interpretation - Wikipedia

    en.wikipedia.org/wiki/Rhythm_interpretation

    A premature atrial pacemaker has a regular underlying rhythm however there is a premature beat which can be identified by an irregular p wave with a different size, shape, and direction often found within a T wave, the PR interval is generally normal however can be hard to measure, the QRS complex is premature for the PAC, but is generally normal.
