Flutter: My guess is that you're experiencing irregularity of heart rhythm in the form of extrasystoles(premature heart beats). If this is the case you would notice an irregularity in your pulse at the wrist or over the neck(carotid artery). To document this, wearing an outpatient Holter Monitor would record your heart rhythm and show what's happening when you note that symptom. Stomach distenson can cause

VAGUS NERVE: This is stimulated by a number of things involving swallowing, digestion, holding breath, tense abdomen, etc. The nerve slows the heart beat. There is often skip beats with this. There is often a rebound rapid heart beat when it ends. It usually lowers blood pressure slightly.
