Rapid Heart Rate

High caffeine intake might have stimulatory effects that can make your heart beat more quickly. Young people who drank energy drinks with high caffeine dosages have been linked to atrial fibrillation, which is an altered heartbeat rhythm.

In one case study, a woman who tried suicide by taking a significant amount of caffeine and powder suffered an extremely fast heartbeat, kidney failure, and other severe health problems. However, not everyone appears to have this impact. In fact, some people with heart conditions may be able to take high doses of caffeine without suffering any bad impacts. In a controlled research, normal heart rates and rhythms were maintained in 51 patients with heart failure who drank 100 mg of coffee each hour for five hours. Regardless of the conflicting study results, you should think about reducing your consumption if you notice any changes in your heartbeat or rhythm after drinking caffeinated beverages.
