Drinking Puzzle

From the Nova Monitor (from somewhere else):

Two men walk into the bar and each order a vodka tonic on the rocks. One slams down his drink immediately, much to the shock of the barkeeper and the other man. The other man takes his time with his drink, but before he can finish it, he falls over dead. The man who drank his drink quickly was fine. Why caused the one man’s death, and why didn’t the other die as well?
