Question 1

Why am I having heart palpitations and shortness of breath if my heart tests are normal?

Accepted Answer

Normal cardiac test results do not necessarily mean nothing is wrong. Standard tests evaluate the heart itself but do not screen for digestive triggers like hiatal hernia, bloating, or vagus nerve irritation, all of which can produce real palpitations, irregular heartbeat, and shortness of breath. The gut-heart connection is well-documented but frequently overlooked by conventional cardiology. If your heart workup came back clear yet your symptoms persist, a functional medicine evaluation can identify whether your digestive system is the actual root cause.

Question 2

What is the gastrocardiac reflex and how does it affect heart rhythm?

Accepted Answer

The gastrocardiac reflex occurs when distension, pressure, or irritation in the stomach sends signals through the vagus nerve that disrupt the heart's normal electrical rhythm. This can trigger palpitations, an irregular heartbeat, chest tightness, or even AFib episodes, especially after meals, when lying down, or during bloating. The mechanism is real and measurable, but it is rarely identified in standard cardiac workups because the trigger originates in the digestive system rather than the heart. Root Cause Medical Clinic specializes in finding this connection. Call (727) 335-0400.

Question 3

How does bloating cause shortness of breath and chest tightness?

Accepted Answer

When the stomach becomes distended with gas or food, it can press upward against the diaphragm and reduce its ability to fully expand. This mechanically restricts breathing, producing a sensation of breathlessness or an inability to take a full deep breath. The same upward pressure can also push against the pericardium, the sac surrounding the heart, creating a feeling of chest tightness or pressure. These symptoms often appear in clusters after meals or with significant bloating, and they typically resolve when the underlying digestive issue is addressed. Call Root Cause Medical Clinic at (727) 335-0400.

Question 4

How is digestive-related AFib treated differently from a primary heart condition?

Accepted Answer

When AFib or irregular heart rhythm is being driven by vagus nerve irritation, hiatal hernia, or chronic bloating rather than a primary heart problem, treating the heart alone often provides only partial relief. A root cause approach targets the digestive trigger directly, using manual therapy to address hiatal hernia, dietary changes to reduce bloating and inflammation, and functional medicine protocols to restore healthy vagal tone. Many patients see significant improvement in palpitations and AFib episodes once the gut-heart connection is properly addressed. Dr. Vikki Petersen and the team at Root Cause Medical Clinic in Clearwater specialize in this integrative approach. Call (727) 335-0400.
