Atrial Fibrillation patients often have loads of “Why?” and “How?” questions. Here are answers to the most frequently asked questions by patients and their families. (Click on the question to jump to the answer.)
5. “What is the difference between “Adrenergic” and “Vagal” Atrial Fibrillation? How can I tell if I have one or the other? Does it really matter? Does Pulmonary Vein Ablation (Isolation) work for Adrenergic and/or Vagal A-Fib?“
14. “I have paroxysmal A-Fib with “pauses” at the end of an event. Will they stop if my A-Fib is cured? My cardiologist recommends a pacemaker. I am willing, but want to learn more about these pauses first.” NEW!

4. “Is Atrial Fibrillation different from what doctors call Paroxysmal Supraventricular Tachycardia?”
‘Supraventricular’ refers to the upper part of the heart, the atria. “Tachycardia” means the upper part of your heart is beating faster than normal. “Paroxysmal” means occasional.
“Supraventricular Tachycardia” in clinical practice commonly refers to atrial tachycardia, atrioventricular nodal reentrant tachycardia (AVNRT). Atrioventricular reciprocating tachycardia (AVRT), an entity that includes Wolff-Parkinson-White syndrome. While Atrial Fibrillation is a distinct entity classified separately.
The term “Supraventricular Arrhythmia” most often is used to refer to Supraventricular Tachycardias and Atrial Flutter. In practice, “Supraventricular Tachycardia” is often used loosely to include all arrhythmias in the Atria, including A-Fib.
