I was running with my friend last night. He saw that I was wearing a sports watch and asked me if this worked? I said that middle-aged people should exercise more slowly. They can’t go 1,000 meters like when they are young. Running through the heart rate of the watch can not only understand the degree of exercise, but also prevent some heart problems.

He told me that he had actually worn a sports watch before, but he always reminded him that his heart rate exceeded the standard. He went to the hospital to see it, and there was no problem with the electrocardiogram. However, sometimes he still feels that his heart is beating fast, and he is still somewhat uneasy.

I suggest that if he has time, he can go to the hospital to do a 24-hour electrocardiogram or exercise electrocardiogram to understand the complete condition of his heart. As for the problem of his own feeling of fast heartbeat, the test results shall prevail.

Since we talk about the heart today, let’s talk about these issues below

I often feel that my heart is beating fast, is it stressful or has a heart problem?

In this case, it is recommended that when you feel your heartbeat is fast, you can measure the pulse first, preferably by pressing with your fingers. In addition to measuring the number of beats per minute, you should also pay attention to whether the heartbeat is regular and record it.

If you have a sports watch or a sports bracelet, it will be easier to measure. In addition, some sports watches also have a simple ECG function. You can test it to see if there is any abnormality.

I feel that my heartbeat is a bit fast, but it may not be really fast. When it happens, I measure and record it. You can use the data to know if I feel fast or if my heartbeat is really fast.

Even if the heartbeat is sometimes really fast, if the beating is regular, in most cases, the sympathetic nerves are overexcited due to factors such as high stress. In such cases, there is no need to worry; however, if the heartbeat is found to be irregular, it is recommended to further Go to the hospital’s cardiologist to see a doctor to avoid danger.

When people experience chest tightness and gasping symptoms when they are active, must they have cardiovascular problems?

Many people have such symptoms or even feel weak, and they think it must be a cardiovascular problem. In fact, although we cannot rule out this possibility, this is not the only answer. For example, patients with anemia cannot carry enough oxygen to the Chest tightness can also occur in various parts of the body, not a cardiovascular problem.

In addition, lung problems, such as patients with chronic obstructive pulmonary disease, can also easily cause symptoms of chest tightness and asthma; some people have normal heart and lung function, but they rarely exercise regularly. If they suddenly exercise, it is actually an extra burden on the heart and lungs. For example, if you usually take the elevator and climb up to the 6th floor at once, you will be out of breath, and even those who are weak may need to take a break.

Clinically, there is also such a situation. Someone complained that his heart was weak. After the doctor checked and ruled out the heart problem, he did not believe the doctor’s diagnosis, because he went to the Internet to check that it was a “heart problem”, and even instructed the doctor. It should be done with echocardiography or CT examination. In fact, this is not the correct attitude. What examination and diagnosis should be done should be judged by the doctor. Most of these problems are caused by “suspicious heart disease”.

When should an exercise ECG be done?

The purpose of the exercise ECG is to increase the oxygen consumption of the heart, to find out the problems that the heart does not have at rest.

Generally speaking, the blood flow will be reduced only if the coronary vessels are blocked by more than 75%, but even if it is blocked so much, if the consumption is not enough, the symptoms of insufficient blood flow may not appear. It is like a person’s income decreases, but If you don’t spend a lot, you may not feel that you don’t have enough money all of a sudden.

Exercise ECG is to increase the burden on the heart, just like forcing a person to spend more to know how much money he has in his pocket, that is, to confirm whether the blood flow supplied is insufficient.

As the weather heats up, do I need to adjust my blood pressure medication dose?

My friend belongs to the three-high group. The weather is hot. He feels that his blood pressure is relatively stable. He wants to reduce the medication. I let him observe it for a while.

The adjustment of blood pressure lowering drugs should be based on the condition, and should be discussed with the doctor first, and should not be adjusted arbitrarily. Therefore, it is very important for the patient to regularly measure the blood pressure at home for a long time. The doctor must also adjust the dose based on these data.

Generally speaking, the blood circulation of the human body is better in summer, and the blood pressure will be relatively stable, but the impact of weather changes on hypertensive patients may not only be stable, but also increase variables.

In addition, the factors affecting blood pressure changes are not only the weather. Some patients may have a little high blood pressure when they are busy due to a lot of work recently, but they will drop after the work. It is not necessarily that the current dose is not suitable for them, so the patient cannot reduce the blood pressure record , so that it can be provided to the doctor as a reference for medication during regular inspections.

Early ventricular contractions are found during physical examination, do I need treatment?

In fact, this problem is not uncommon. The occurrence of premature ventricular contractions is palpitations in the feeling of many people.

The beating of the heart is directed by a set of conduction systems. The sinus node above the right atrium is the commander-in-chief of the heart. After discharge, the atrium contracts and the blood is pumped to the ventricle, and then the electrical signal is transmitted to the atrium between the atrium and the ventricle. The re-discharge causes the ventricle to contract and pump blood to the aorta or pulmonary artery, so that the volume of blood pumped by the sequential contraction can be used by the body most efficiently.

Early ventricular contraction, also known as premature contraction, means that the ventricle jumps out before waiting for the command from the superior, just like someone grabbing a beat when singing, so the amount of blood pumped out is less than normal, and the work efficiency is not good. There will be a feeling of emptiness in the heartbeat, and you may not be able to detect the beating according to the pulse, which is a kind of arrhythmia. After the early contraction, the diastolic period between the next heartbeat is longer, and more blood returns to the heart. Therefore, the next time the heartbeat returns to normal, the amount of blood pumped out will increase, which will make people feel particularly strong, and Feeling of heart palpitations.

The potential instability of premature contractions originates from the ventricle. It may not be a problem with the structure or function of the heart. For example, when the sympathetic nerve is too excited, the potential may be unstable. Therefore, it may occur when staying up late, under stress, or drinking tea or coffee. It is also easy to stimulate the sympathetic nerves. At this time, the first thing is to adjust the living habits.

For this kind of problem, doctors usually observe the heart function. If there are problems such as high blood pressure or myocardial hypoxia, such obvious causes should be dealt with. If the heart function is not abnormal, but the arrhythmia occurs frequently, and the patient feels uncomfortable, drug treatment for the arrhythmia will also be given, especially if there are more than 3 consecutive early ventricular contractions, called ventricular frequency pulse, The patient will not only have obvious discomfort, but even faint, and must receive treatment.
