Question 1

What is vagal AFib and how is it different from typical AFib?

Accepted Answer

Vagal AFib is a specific pattern of atrial fibrillation that is triggered by the vagus nerve rather than a primary electrical problem in the heart. It typically occurs after meals, at night, or while lying down, times when the digestive system is most active and vagal tone is highest. Unlike typical AFib, which may occur with exertion or stress, vagal AFib often improves with increased heart rate and worsens at rest. Recognizing this distinction is critical because the treatment approach differs significantly. Dr. Vikki Petersen at Root Cause Medical Clinic specializes in identifying vagal AFib.

Question 2

Can digestive problems like hiatal hernia actually cause AFib?

Accepted Answer

Yes. A hiatal hernia places the stomach in close anatomical proximity to the heart and diaphragm. When the herniated stomach presses on the vagus nerve or diaphragm, it can disrupt the electrical signals that regulate normal heart rhythm, triggering AFib episodes. This mechanical connection is frequently overlooked by cardiologists because it lies outside the cardiovascular system. At Root Cause Medical Clinic, we assess and treat hiatal hernia as a potential driver of AFib using our non-surgical Root Cause Method. Call (727) 335-0400.

Question 3

Why do my AFib symptoms get worse after eating or when lying down?

Accepted Answer

Worsening AFib after meals or when lying down is a classic sign of vagal AFib driven by digestive dysfunction. After eating, the stomach expands and can compress nearby structures including the vagus nerve and diaphragm, triggering arrhythmia. Lying down similarly increases pressure on these structures. These positional and meal-related patterns are important diagnostic clues that the root cause may be gastrointestinal rather than purely cardiac. Root Cause Medical Clinic evaluates these patterns as part of our comprehensive functional medicine assessment. Call (727) 335-0400.

Question 4

What does a root cause approach to AFib treatment look like?

Accepted Answer

A root cause approach to AFib begins with identifying whether the arrhythmia is being driven by a digestive trigger such as hiatal hernia, gut inflammation, or vagus nerve irritation. Treatment may include manual therapy to address the hiatal hernia, dietary changes to reduce gut-related inflammation, functional testing to identify food sensitivities or nutritional deficiencies, and targeted protocols to support healthy vagal tone and heart rhythm. This approach aims to reduce AFib episodes naturally without relying solely on antiarrhythmic medications. Dr. Vikki Petersen and her team in Clearwater specialize in this integrative method.
