Dr. Sam, a retired MD, wrote to caution A-Fib patients that local anesthesia containing epinephrine can trigger your A-Fib. Local anesthesia (with Epi or Adrenalin) is used by dentists and emergency room personnel.
Dr. Sam writes:
At the Dentist: “This past year I had to have a dental implant and bridgework requiring that I have Local Anesthesia several times. The dentist uses local anesthesia with Epinephrine (Epi or Adrenalin) to numb your mouth.
Epinephrine (Epi or Adrenalin) is one of the drugs EPs can use when completing a catheter ablation—they try to trigger A-Fib to check that their ablation scars for working. So dental local anesthesia with Epinephrine (Epi) potentially can trigger A-Fib. I found very little info online about this and no studies had been done about dental anesthesia with Epi & A-Fib.
My EP said he thought it would be OK to use. So I had it, and within 30 minutes I was in A-Fib which lasted about 20 minutes and then I went back into NSR.
From then on I requested that my dentist use only local anesthesia without Epi, and I had no more A-Fib episodes. Dentists like to use local anesthesia with Epi because it lasts longer and reduces bleeding locally.
Discuss with your dentist if you think you’re sensitive. Tell him/her you have A-Fib.”
At the Opthamologist: “The drops that the eye doctor uses to dilate your eyes are similar to Adrenalin. Discuss with your eye doctor if you think you’re sensitive. Tell him/her you have A-Fib.”
At the Emergency Room: “In the ER doctors use local anesthesia with Epi to sew up lacerations and/or to do small surgical procedures requiring local anesthesia, because it reduces bleeding locally and lasts longer. Tell your doctor you have A-Fib and discuss your concern that the use of local anesthesia with Epi may trigger your Atrial Fibrillation.”
Thanks Dr. Sam for sharing this warning about Epinephrine containing products.
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?
