The gut has its own mini brain, the enteric nervous system, which not only controls the gut, but is directly connected to the heart, lungs and main brain via the vagus nerves. It seems to have considerable influence over all 3 organs. Digestion needs additional blood flow which can trigger an increase in heart rate.
Chocolate contains caffeine and theobromine both of which may trigger arrhythmias, palpitations and PVCs and may increase the heart rate. It also produces nitric oxide which dilates blood vessels causing a drop in BP which may also raise the heart rate. This doesn't mean chocolate is bad for you in moderation. Dark chocolate at 10-20mg/day reduces the risk of heart attacks and ischemic strokes, but it does have side-effects.
However, I suspect at least some of the symptoms have more to do with anxiety than eating and chocolate, or are amplifying them.
