Is roemheld syndrome a credible diagnosis? what could cause palpitations when refluxing with normal scope and work-up?

Probably: There can be a relationship between distension of the stomach by gas buildup or a large meal and the development of cardiac arrhythmias like benign premature beats causing transient palpitations. The vagus nerve may also play a role in the stomach disorders and palpitations. Wear an outpatient holter monitor to record your heart activity when you experience palpitations and identify the cause.
