What substances can exacerbate atrial fibrillation?

Caffeine and nicotine are known stimulants that can increase heart rate and potentially trigger or exacerbate episodes of atrial fibrillation. Caffeine, found in coffee, tea, and various energy drinks, can heighten excitability in the atrial tissue, leading to an increased risk of arrhythmias for susceptible individuals. Nicotine, commonly consumed through tobacco products, can also stimulate the heart and contribute to electrical instability, making it a significant factor in exacerbating atrial fibrillation.

While alcohol and heavy metals, corn syrup and sugars, and herbal supplements may have various effects on cardiovascular health, they are not as directly linked to the acute exacerbation of atrial fibrillation in the same way that caffeine and nicotine are. This understanding emphasizes the importance of monitoring the intake of known stimulants to help manage atrial fibrillation effectively.
