I drank four 20 oz. red bulls and now my heart feels funny, what should i do?

Hang in There: Each redbull is 80mg of caffeine, so basically, you had about 760mg of it. The half-life of caffeine is 5-6 hours. You'll be down to the level of a couple cups of coffee within 12 or so hours. Caffeine toxicity is mostly due to cardiac arrhythmias, but that doesn't usually happen until >3 times the amount you've had, and direct toxicity not until ~25x. Consider this a lesson learned :).

Arrhythmia: The large dose of caffeine you ingested with the red bulls is likely driving your heart fast and maybe elevating your blood pressure. It will take hours for this to go away. If you're really uncomfortable go to er and let them check you.
