2. Wikipedia:Osmosis/Atrial fibrillation - Wikipedia

   en.wikipedia.org/.../Atrial_fibrillation

   Persistent AF episodes can last for quite a long time - weeks to months, and when the AF episodes last beyond 12 months, it’s known as long-standing persistent AF, and “permanent AF” is what’s it’s called when the patient and clinician make a joint decision to not attempt to stop the rhythm.

3. 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]

4. Atrial fibrillation - Wikipedia

   en.wikipedia.org/wiki/Atrial_fibrillation

   As atrial fibrillation becomes more persistent, the junction between the pulmonary veins and the left atrium becomes less of an initiator and the left atrium becomes an independent source of arrhythmias. [18] High blood pressure and valvular heart disease are the most common modifiable risk factors for AF.

5. Palpitations - Wikipedia

   en.wikipedia.org/wiki/Palpitations

   The cardiac etiologies of palpitations are the most life-threatening and include ventricular sources (premature ventricular contractions (PVC), ventricular tachycardia and ventricular fibrillation), atrial sources (atrial fibrillation, atrial flutter) high output states (anemia, AV fistula, Paget's disease of bone or pregnancy), structural ...

6. Pacemaker syndrome - Wikipedia

   en.wikipedia.org/wiki/Pacemaker_syndrome

   That's due to increase in left atrial pressure and left ventricular filling pressure, which is due to decreased cardiac output caused by dyssynchrony in atrial and ventricular contraction. ANP and BNP are potent arterial and venous vasodilators that can override carotid and aortic baroreceptor reflexes attempting to compensate for decreased ...

7. Automatic tachycardia - Wikipedia

   en.wikipedia.org/wiki/Automatic_tachycardia

   Ectopic atrial tachycardia (EAT), also known as automatic atrial tachycardia, is an arrhythmia caused by both atria with abnormally fast atrial rates. [12] The ectopic focus's firing rate is quicker than that of the sinus node, and it overrides normal sinus node activity. Heart rates in children and adolescents can range from 130 to 210 beats ...
