First, because caffeine in coffee itself has the effect of generating excitement, drinking strong coffee or drinking too much will lead to an accelerated heartbeat; But because you are not used to drinking coffee or rarely drink coffee, so the feeling of palpitation and rapid heartbeat will be more intense.

Solution: Drink lightly or less in the future.
