Some people say that drinking coffee makes your heart beat faster.
However, studies have shown that drinking coffee is unlikely to increase premature atrial contractions (PACs).
Atrial premature contraction is an irregular heart rhythm caused by premature beats in the upper chambers of the heart, the atria.
When the atria produce electricity faster than the expected beat, causing the heart to beat It may not feel unpleasant, but it is normal for a healthy heart.
Some people feel like skipping one heartbeat or adding one heartbeat.
A research team led by Professor Gregory Marcus, a cardiologist at the University of California, San Francisco, USA, conducted an experiment on 100 healthy coffee drinkers to see how irregular the heart beats when drinking coffee, and found this fact, HealthDay News. ) was reported on the 25th.
Most of these people drink around one cup of coffee a day.
For two weeks, the research team abstained from drinking caffeinated coffee on some days and no caffeine on other days, and that they always wore an electrocardiogram piece that could record the electrical activity of their heart.
As a result, the number of premature heart contractions was 58 on the day they drank caffeinated coffee, and 53 on the day they didn’t consume caffeine, almost no difference.
However, the number of premature ventricular contractions (PVC) was slightly higher on days when coffee was consumed than on caffeine-free days.
Premature ventricular contractions are premature contractions of the lower chambers of the heart, which increase the risk of heart failure if frequent.
The number of premature ventricular contractions was 154 on the day they drank caffeinated coffee and 102 on the non-caffeinated day.
Regarding this, Professor David Kao, a cardiologist at the University of Colorado College of Medicine, found that the number of heartbeats per day is around 100,000, he explained that only
In addition, the average sleep time per day on the day when caffeinated coffee was consumed was 397 minutes, which was 35 minutes shorter than the day when caffeine was not consumed.

If you are worried about changes in your heart rate that appear when you drink coffee, you need to look at what happens when you abstain from coffee, the researchers suggest
The results of this study were published in the latest issue of the New England Journal of Medicine, an American medical journal.
