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.)
1. Causes: “Why does so much Atrial Fibrillation come from the Pulmonary Vein openings?”
Related Question: “What causes Paroxysmal A-Fib to turn into Persistent (Chronic) A-Fib?”
Related Question: “A-Fib and Flutter—I have both. Does one cause the other?”
2. Hereditary: “Is my Atrial Fibrillation genetic? Will my children get A-Fib too?”
3. PSVT: “Is Atrial Fibrillation (A-Fib) different from what doctors call Paroxysmal Supraventricular Tachycardia?”
4. Adrenergic/Vagal: “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?”
5. Stiff Heart: “I’ve heard about ‘stiff heart’ or diastolic dysfunction. When you have A-Fib, do you automatically have diastolic heart failure? What exactly is diastolic dysfunction?”
6. Stem Cells: “I’ve read about stem cells research to regenerate damaged heart tissue. Could this help cure A-Fib patients?”
7. EF: “What is the heart’s ejection fraction? As an A-Fib patient, is it important to know my EF?”
8. Anesthesia: “I read that the local anesthesia my dentist uses may trigger my A-Fib. Why is that?”
9. Fibrosis: “How can I determine or measure how much fibrosis I have? Can something non-invasive like a CT scan measure fibrosis?”
10. Treatment Options: “My surgeon wants to close off my LAA during my Mini-Maze surgery. Should I agree? What’s the role of the Left Atrial Appendage?”
Related Question: “My cardiologist recommends a pacemaker. I have paroxysmal A-Fib with “pauses” at the end of an event. Will they stop if my A-Fib is cured? I am willing, but want to learn more about these pauses first.”
Related Question: “My EP won’t even try a catheter ablation. My left atrium is over 55mm and several cardioversions have failed. I am 69 years old, in permanent A-Fib for 15 years, but non-symptomatic. I exercise regularly and have met some self-imposed extreme goals. What more can I do?

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), and 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.
