ABSTRACT

The interaction between arrhythmia episodes and certain lifestyle factors such as obesity and alcohol is well established. There is significant public and professional interest in the role of caffeinated beverages such as coffee, tea, and energy drinks in cardiovascular health. However, many widely held beliefs are not supported by evidence. This study provides a comprehensive review of the impact of caffeinated beverages on cardiac rhythm.
