The researchers who discovered the antiarrhythmic effects of coffee (caffeine) were somewhat surprised at their findings. They had expected to find the opposite results. Caffeine is a stimulant. It makes its consumers awake and alert, and it improves performance.147 Coffee (caffeine) is commonly associated with disruption of cardiac rhythm.
