I have the exact same symptoms and the same negative work up like you, Herve. What did the arrythmia center show? Did you ever resolve it?
I too have heart flutter directly associated with gas in the stomach. I think there is a big link between afib and stomach problems. Burping usually releaves this. It might be pressure on the Vagus nerve as you mentioned. Many afib forums are full of people saying this very same thing, but the Doc's don't seem to want to check into it much. Odd.
I have also developed a condition known a paroxysmal tachycardia at the same time that my abdominal pain appeared. I am convinced there is a correlation between the two. I get severe palpitations early in the morning and take tenormin to regulate this. The vagus nerve, I believe, has something to do with this. Inflammation has an effect on this nerve. I am investigating this theory further with my surgeon.
Hello - thanks for asking your question.
You note palpitations and a bloating feeling in your stomach. Echocardiogram, stress test, blood work, event recorder all non-revealing.
I assume they tested thyroid levels in the blood work.
An arrhthmia center is a wise next move, considering the negative tests so far. You will likely be considered for an EP test (electrophysiology) to make sure you don't have a serious arrhythmia causing your symptoms. If an arrythmia is found, it can be ablated at an arrythmia center.
I am unaware of a GI disorder that can directly cause palpitations. Some suggest that the chest discomfort caused by GERD or dyspepsia may trigger palpitations. In any case, the upper GI discomfort can be further evaluated with an upper endoscopy. This would also look for inflammation or ulcers that may be causing your symptoms. I would also consider an ultrasound to rule out gall bladder disease. If those tests are negative, a 24-hr pH test can be performed to give a definitive diagnosis of GERD.
Followup with your personal physician is essential.
