IT man drinks a cup of coffee and his heart beats like a roller coaster.

In order to refresh my stomach after a cup of super-strong coffee, I suddenly had chest tightness and suffocation, and my heart beat so fast that I thought it was a heart attack. I swallowed two quick-acting heart-saving pills to slowly recover. Yesterday, the man rushed to the hospital to check his heart, but was told by the doctor that he was "allergic to caffeine", as long as he didn't touch coffee in the future.

Mr. Yan, 38, works for an Internet company. Half a month ago, the company took on a project. He led his team to work overtime until two or three o'clock in the morning. Sleeping in the office at night, eating three meals a day depends on takeout. The day before yesterday afternoon, he was going to drive out to run errands, but his eyes were too sleepy to open. To cheer him up, he quickly made a cup of super strong coffee.

More than ten minutes later, my heart felt very uncomfortable, my heart beat like a roller coaster, and my chest was stuffy and breathless. Mr. Yan quickly pulled over, found out that he had swallowed two quick-acting heart-saving pills in the car, and rested on the steering wheel for half an hour before he recovered.

My father had coronary heart disease, and my grandfather also died of a heart attack. He was worried that he would have a heart attack. Mr. Yan kept a quick-acting heart-saving pill all the year round. Early yesterday morning, Mr. Yan went to the Emergency Department of Wuhan Asian Heart Hospital. Zhang Yong, deputy director, found through various examinations that there was no heart problem.

After detailed consultation, the receiving doctor thought that the problem was the espresso. When he heard that he might be allergic to caffeine, Mr. Yan was very worried: he had drunk coffee before, and there was no discomfort. Zhang Yong explained that staying up late and working overtime for a long time, the body was in a state of extreme fatigue, highly concentrated while driving, and drank exciting coffee, which led to excessive excitement of the sympathetic nerves, which at the same time increased the burden on the heart and led to a sudden increase in heart rate. "if you feel uncomfortable with your heart when you drink coffee, it will be over if you don't drink it later." Zhang Yong wrote a prescription.

Professor Bao Mingwei, director of the fourth Department of Cardiology in Renmin Hospital of Wuhan University, told reporters that the caffeine contained in coffee has the effect of exciting sympathetic nerves and will cause the heartbeat to quicken. This kind of palpitation is the normal response of the heart. It is the same thing as going up the stairs and racing after running. Most of them are temporary and will soon return to normal, and will not cause any bad effect on the heart.

Bao Mingwei said that coffee and strong tea are indeed refreshing, but when you are overtired, do not have a good rest, weak or in a bad mood, the body becomes particularly sensitive to caffeine, even if you don't drink much. it can also cause an "overload" in the heart.

Outpatient statistics show that more than half of cardiovascular accidents are related to fatigue and staying up late. Professor Bao Mingwei said that coffee is just an inducement, like "the last straw that crushes the camel."

Bao Mingwei points out that although caffeine is refreshing, it only lasts for a short time and consumes B vitamins related to nerve and muscle coordination in the body. People who lack B vitamins are more likely to get tired. Tired to rely on coffee refreshing, develop the habit of relying on coffee, need more and more, but the effect is getting worse and worse, forming a vicious circle.

Zhang Yong warned that people with premature beats and arrhythmias had better not touch coffee. There are also some people who have diarrhea and insomnia as soon as they drink coffee, and these people should drink less or not. There is no need to panic when there is something wrong with your heart after drinking coffee, drink more boiled water to help your metabolism, and then lie down and have a rest, which will soon be relieved.
