Why does a person s heart beat faster and slower? What to do?

It is normal for the heart to beat sometimes fast and sometimes slowly, depending on the needs of the human body. When the sympathetic nerve is excited, the heart beats faster, and when the vagus nerve is excited, the heart beats faster. When the heart needs to work more during the day, the sympathetic nervous system will be excited, which will make the heart beat faster.

When the heart beats less frequently at night when it needs to rest, the vagus nerve regulates the heart so that the heart can rest smoothly and quietly, so the sympathetic and vagus nerves control the heartbeat. Not only that, neurotransmitters and baroreceptors such as electrolytes, carotid sinus baroreceptors, and parabulbar receptors in the kidney will make the heart beat fast and slow, which is a normal physiological feedback mechanism.

The heartbeat of a normal person is originally fast and slow, and the heartbeat is not like the fixed frequency of watches and alarm clocks. A person's heartbeat is generally within the range, even if it is a normal level, the normal heartbeat is about 60-100 minutes, and the heartbeat level within this range is considered to be a normal heartbeat. Of course, everyone's heartbeat feels different, some people's heartbeats are more comfortable for 60 minutes, and when they reach 80 minutes, they feel flustered and uncomfortable, and they think that their heartbeats are faster.

And some people's hearts beat at 90 beats for a long time, which is a fast level, and they don't feel it. Therefore, when you feel that your heart rate is fast or slow, the first thing you should do is to measure your own pulse, if the number of pulses counted is about 60-100 minutes, this is a normal pulse rate, and you don't need to be too nervous. It may be a little excited or not rested well, but you can generally adjust it by paying attention to rest.

Of course, although some people have a bad heartbeat, within the normal range, but the heartbeat is very irregular, at this time, you may need to pay attention to whether there is a combination of arrhythmia, such as premature beats, tachycardia, etc., which can be further clarified through electrocardiogram examination.

Generally, when the heartbeat is fast, the heartbeat will only increase when the sexual mood is particularly excited, for example, when facing the person you like, the heartbeat will also increase at this time. In fact, there is no need to deliberately control it, after all, there are not many things about men's heartbeats. Just keep your emotions in check.

In fact, we should all be able to understand, we can see in our actual life that there are many things that we need to pay attention to, if we don't pay attention, it is likely to have a more serious impact on our body, that is to say, the heart beats too fast or too slow, a harm to the human body is still relatively large. If the heart rate is too fast, it is very likely to cause one of us to develop poorly, and it may also make ours. The heart rate has become faster, which makes us all have some symptoms at night, so this is also a more important point.

Then we're in the actual. In the process of development, we can feel that these are more serious, and we also need to better deal with this disease.

Of course, if our heart rate is too fast, there is a high probability that there will be a general type of heart disease and a type of heart disease, which is not good. That's why we all need to be able to feel it. The other is.

If the mind is too fast and too slow, it will have a significant impact on our body. There is a normal heart rate is a relatively good one, like 1 minute. How much, such a physical change is indeed more important, then 1 minute like 120 is more important, 1 minute 70 to 80 is the most normal.

You can feel this, so for these people who have an irregular heartbeat. Or people who are too fast or too slow. They are likely to have a more significant impact, and one that needs to be felt by all of us.

I still hope that everyone can better ensure their physical health, because nothing is more important than our mental health. All in all, we need everyone to be able to see this, no matter what, we still need to ensure that we have a healthy state of development, and it is indeed a very important point of content, all in all, I hope that everyone can ensure a healthy development of themselves.

Fast or slow heartbeat will have a certain impact on people's physical health, resulting in serious cardiovascular and cerebrovascular diseases, insufficient blood supply to the heart, serious fatigue in the body, and poor spirits. The normal rhythm of the heart rate is to stay between 110 and 140 per minute.

It can cause problems with blood vessels, cause physical fatigue, and easily cause harm to other organs of the body, and the normal heartbeat is 60 100 beats per minute.

If the heartbeat is too fast or too slow, it is very harmful to our body, because it will cause us to have heart disease, and the normal heartbeat is generally around 70 or 80.

The normal number of heartbeats is 60-100 minutes, and less than 60 minutes is called bradycardia, also known as slow heartbeat.

What everyone cares about the mostGeneralYes: What causes my heart to beat slowly? Need **?

There are many reasons for a slow heartbeat, so let's talk about the common causes of slow heartbeat and how to deal with them.

1.Physiological slow heartbeat

This type of slow heartbeat is common in sports enthusiasts and manual workers. The resting heart rate of an athlete can be 40-50 beats, and the heart rate of a normal person can be as slow as 40 beats when sleeping. Slow heartbeat if physiologicalGenerally, no special treatment is required

2.Took medications to slow down your heart rate

These include receptor blockers (betalox, bisoprolol, carvedilol), antiarrhythmic drugs (amiodarone, arrhythmia), non-dihydropyridine calcium antagonists (diltiazem), digitalis drugs (digoxin, cediran), etc. The way to deal with it is simple, ieDiscontinue or reduce the dose under the guidance of a physician

3.Severe myocardial ischemia

For example, myocardial infarctionIt can cause severe bradycardia, which is mostly reversible due to ischemia-induced bradycardia, but may worsen at any time, and temporary pacing and revascularization should be performed as soon as possible.

4.Electrolyte imbalances

High potassium, calcium, and magnesium can all cause slow heartbeat, with hyperkalemia being the most common. Electrolyte imbalancesUsually comorbidities of other conditions(such as acute and chronic renal insufficiency), it is necessary to actively seek and deal with it**.

5.Vagus nerve hyperfunction

The vagus nerve is the nerve fiber that sends out from the brain to innervate the heartbeat. When excited, its terminals release a substance called "acetylcholine", which acts as a depressant to the heart and slows the heartbeat. Slow heartbeat caused by vagus nerve dysfunction is usually transientGenerally, no special treatment is required

6.Hypothyroidism

It is a less common condition that causes a slow heartbeat** and is usually needed in such patientsTake thyroxine tabletsSubstitute**.

A general principle of treatment is:

If the heart beats slowly, a detailed medical history should be provided to the doctor, and an electrocardiogram should be actively performed to:Look for what's causing your slow heartbeat

If cardiac output is insufficient due to slow heartbeat, the means mainly include drugs, temporary pacing and permanent pacing

A person's normal heartbeat should be sinus rhythm (60 out of 100 points). Slowness is called "sinus bradycardia", and more than 100 is classified as "sinus tachycardia". The causes of this rapid heart rhythm are usually as follows:

1. Exercise; 2. Lack of sleep; 3. Cold and fever; 4. Inflammatory lesions, etc. 1. You have been working overtime recently, and you only went to bed at 1 o'clock at night, and if you don't get enough sleep for a long time, there will also be changes that affect your heartbeat, but it is not the main reason, do you have a cold? Young people should pay special attention to one point, due to work reasons, many people do not pay much attention, thinking that a cold is a minor disease, but they do not know that a small cold is not timely**, coupled with insufficient rest, it is easy to cause the virus to enter the heart, causing acute myocarditis, so it is very troublesome.

Second, you can obviously feel the heartbeat vibrating a lot, when sleeping, the quilt can shake the problem is actually non-existent, because your feeling, under normal circumstances, is a feeling when entering the bed, calm rest, no matter when you are, only if you use your own hands to feel the carotid artery, the left heart part and other arteries and blood vessels, you will have a sense of beating, which is a normal phenomenon, if the arteries and blood vessels can not be felt and touched, hehe, this person should be his heart ejection function, There is a problem with the output function. Suggestions: 1. Adjust the rest time, pay attention to keeping warm, and prevent colds.

2. If there is no recovery within 3 to 5 days, an electrocardiogram should be done, and at the same time, another (blood) myocardial enzyme test should be done to determine whether you have suffered from acute myocarditis or myocardial ischemia.

The normal human heart rate is 60 to 100 beats. Under normal circumstances, a person's rapid heartbeat can be caused by smoking, drinking tea or coffee, drinking, physical activity and emotional agitation!

Certain fevers, hyperthyroidism, anemia, shock, myocardial ischemia, congestive heart failure, and the use of drugs such as epinephrine and atropine can also be caused! (Of course, this is not under normal circumstances, just by the way).

Hello, bradycardiac rate is a pathological phenomenon caused by cardiac changes that cause abnormal slowing of pulsation. The normal number of heartbeats is 60 to 100 minutes, and less than 60 is called bradycardia. 1.

For people who do not have heart discomfort, the pulse is 50 60 minutes, this sinus bradycardia, which is mostly physiological, that is, a normal phenomenon, do not worry about affecting health, and do not need to **. 2.For people with heart discomfort, pay attention to the number of pulses when they are usually calm, and then count the number of pulses when the heart is uncomfortable, if the pulse rate is lower than usual every time you are uncomfortable, it means that your discomfort is caused by slow heart rate, and you need to install a pacemaker to speed up the heart rate in severe cases.

You can also check the 24-hour ECG first to see how much slowest the heart rate is. If the speed of the heart has heart discomfort, it does not matter, and the pulse is 50 to 60 minutes, it means that there is no need for slow heart rate, but other tests are needed to confirm whether you have heart disease.
