Early atrial contraction refers to an irregular heart rhythm caused by an early beat in the upper part of the heart, the atrium.It may feel uneasy when the atrium generates electricity earlier than the expected time of beat formation, but it is normal for a healthy heart.Depending on the person, I feel like I’m skipping one heartbeat or adding one heartbeat.Health Day News reported on the 25th that a research team led by Professor Gregory Marcus, a cardiologist at the University of California, San Francisco, tested 100 healthy people who drink coffee to see how much irregular heartbeat occurs when drinking coffee.Most of these were people who drank about one cup of coffee a day.For two weeks, the researchers tried to avoid drinking caffeine coffee on some days and caffeine on others.They were always accompanied by an electrocardiogram patch that could record the electrical activity of the heart.
As a result, there was little difference, with 58 early heart rate contractions on the day of caffeine coffee and 53 times on the day of no caffeine consumption.Frequent early atrial contraction in older adults can lead to atrial fibrillation, a common form of arrhythmia.Atrial fibrillation is a phenomenon in which the heart rate rises sharply to more than 100 times per minute as the atrium sometimes contracts at a very high speed, becoming thin like jelly in a bowl.Atrial fibrillation in the left atrium can cause blood to accumulate and form blood clots.This blood clot is carried into the bloodstream through the left ventricle, which pumps blood all over the body, drifts around, and blocks cerebral blood vessels, leading to stroke.However, the number of prime ventricular contractions (PVCs) was slightly higher on the days of drinking coffee than on the days of not consuming caffeine.The number of early ventricular contractions was 154 times on the day I drank caffeine coffee and 102 times on the day I didn’t drink caffeine.
Early ventricular contraction is the occasional early contraction of the ventricle, the lower part of the heart, and frequent increases the risk of heart failure.David Kao, a cardiologist at the University of Colorado at the University of Colorado, points out that, given that the number of heartbeats per day is about 100,000, the number of early ventricular contractions on caffeine-free days is only 0.15% of the total heart rate.In addition, on the day I drank caffeine coffee, I had a bit of physical activity.
On the day of drinking coffee, the average number of steps taken per day was 10,646 steps, and on the day of not consuming caffeine, 9,665 steps.The number of steps was measured by the smart watch Fitbit worn on the wrist.In addition, the average daily sleep time on the day of caffeine coffee was 397 minutes, 35 minutes shorter than 432 minutes on the day of no caffeine was consumed.The overall results show that coffee drinkers need to adjust the amount of coffee according to their choices, the researchers explained.For example, when you have difficulty sleeping, limit your coffee to morning coffee, and when you have to move your body, drink coffee an hour in advance.The research team suggested that if you are concerned about changes in heart rate that occur when drinking coffee, you need to look at what happens when you refrain from drinking coffee.The findings were published in the latest issue of the American medical journal New England Journal of Medicine.
