Can a cardiac arrest patient have ventricular fibrillation after being resuscitated? What are the ma

Ventricular fibrillation occurs after cardiac arrest patients are resuscitated. Some patients with myocardial infarction are discharged from the hospital without difference from healthy people; Some patients with myocardial infarction suffer from heart failure and are later hospitalized repeatedly, not for several years; Some patients with myocardial infarction have money spent after surgery, but there is no one; Some patients with myocardial infarction do not have time to go to the hospital, and the person leaves. One of the main reasons for the various outcomes is the attitude towards heart attacks; In fact, if everyone knew they were going to have a heart attack, or already had it, there would be no delay.

Because no one is alive!

But this is because many people, who don't know that they have a heart attack or are about to have a heart attack, think that it doesn't matter, so they lead to different fates; According to statistics, 50% of patients with myocardial infarction in our country do not know that they have myocardial infarction, myocardial infarction, not pain in the heart area, how can 50% of people not know that they have myocardial infarction at all. I'll start with three cases I came across this year and tell you why they don't think so. Aunt Sun has a toothache, and it's fine for a few minutes at a time, especially when she goes upstairs to work.

Buy your own anti-inflammatory drugs to eat, most of the time your teeth don't hurt, and eating and drinking hot water are not affected in any way. So if you don't take it seriously, the result of a sudden toothache is not relieved, accompanied by chest tightness and sweating.

120 hurriedly finished the electrocardiogram showing myocardial infarction and sent him to the hospital, but he was not on the operating table and there was no person. If Aunt Sun knew that she had toothache, angina pectoris, and a precursor to myocardial infarction, would you think she would be able to delay it? Master Yang, who has had back pain for several days, thinks that frozen shoulder, tens of thousands of massages, and feels very effective because back pain is good and bad, and it will not hurt for a long time.

As a result, the sudden back pain was not relieved, accompanied by chest tightness, sweating, and a sense of death. After being sent to the hospital, myocardial infarction was diagnosed, and the large blood vessels were completely occluded, due to the ** night, even if the blood vessels were open. However, I had a huge myocardial infarction, which led to heart failure.

After that, walking becomes a problem because walking makes you breathless, you have trouble breathing, and you are repeatedly hospitalized until a few years later, when your heart failure reaches an advanced stage. You said that if Master Yang knew that the back pain was angina and did not see a doctor earlier, he would have heart failure and become disabled. In the future, he will even gasp for breath while eating, drinking, and sleeping.

Can't he have gone to the hospital sooner?

Ventricular fibrillation will also occur after rescue, because cardiac arrest is very harmful to the heart, and this time is particularly ischemia. Shock, cardiac arrest or unconsciousness may occur.

The vast majority of patients have no aura symptoms and often have sudden onset, a small number of patients can have dizziness, fatigue, palpitations, chest tightness and other non-characteristic symptoms a few minutes to tens of minutes before the onset of the disease, the main clinical manifestations of cardiac arrest are sudden loss of consciousness, heart sounds and aortic pulses disappear, general cardiac arrest for three to five seconds, patients can have dizziness and dark phenomenon, moored for five to ten seconds due to cerebral hypoxia and cause syncope, moored to fifteen seconds can occur Ass syndrome, accompanied by general convulsions and incontinence.

Stopping for 20 to 30 seconds, breathing continues or stops at the same time with pale face or only dry flat mold for 60 seconds, the phenomenon of pain spreading, if it is parked for more than four to five minutes, it is often caused by the lack of oxygen in the central nervous system for too long and causes serious irreversible damage, the auxiliary examination is the most important electrocardiogram, the patient can show ventricular fibrillation within four minutes of cardiac arrest, and the ventricles are still after four minutes.

Possibly. There will be convulsions, sometimes incontinence, paleness, and sometimes cardiac arrest.

Possibly. The face is pale, and it can also cramp, lose its pulse, lose consciousness, and have convulsions.

Cardiac arrest is followed by general convulsions, difficulty breathing, breathing and pulse. Doctors need to monitor the patient's heart in conjunction with an ECG monitor to know if it is cardiac arrest or coma.

Breathing will stop, and there may be no pulse, depending on the patient's condition. You can shout at the patient, and if the patient doesn't respond at all, then the patient is unconscious.

I don't think so; It is necessary to observe whether the patient is breathing and the chest rises and falls, and if there is a breathing action, then it is not a cardiac arrest.

For cardiac arrest patients, why is it important to defibrillate at the mountainside? （）

a.It stops cardiac arrest**.

b.It is not important for cardiac arrest.

c.The success rate of regaining positive reverence is 100% dIt restores a normal heart rhythm.

Correct answer: d

Answer]: b

Analysis: The basis of the incidence of pulmonary heart disease patients is hypoxia, which can cause myocardial hypoxia, which can cause ventricular fibrillation and cause death, so the correct answer to this question is B. Master the knowledge of "epidemiology, ** and pathogenesis of chronic cor pulmonale".

When a patient develops ventricular fibrillation, the preferred measure of rescue is ()aOpen the airways.

b.Open the shot and release the vein.

c.Chest compressions.

d.Endotracheal intubation.

e.Defibrillation (correct answer).

What is the connection between atrial fibrillation and stroke and heart failure?

Atrial fibrillation, or atrial fibrillation, is the most common chronic arrhythmia in cardiology. The heartbeat rhythm of normal people is neat, the frequency is 60 100 minutes, and the heartbeat rhythm of patients with atrial fibrillation can reach 100 160 minutes, which is much faster than that of normal people, and the irregular heartbeat rhythm makes the atria lose its effective systolic function. Many people know about atrial fibrillation, but there is a lack of understanding of this disease, especially patients with atrial fibrillation symptoms that are not obvious or serious, do not pay enough attention to its harms, thus missing the best time and causing serious consequences.

<>So what are the risks of atrial fibrillation? The harm of atrial fibrillation is mainly divided into two categories, one is the impact on heart function, which is manifested by increased heart rate, patients feel palpitations, weakness of limbs, and in severe cases, heart failure. Atrial fibrillation triples the risk of heart failure.

In the Global Atrial Fibrillation Registry, 33% of patients with paroxysmal atrial fibrillation have heart failure, 44% have persistent atrial fibrillation, and 56% have permanent atrial fibrillation.

When atrial fibrillation occurs, one of the most important manifestations is that the atria lose their ability to coordinate contractions and become peristaltic. At this time, the blood in the atria is in a state of stagnation, and the flow is very slow, and it is easy for blood clots to form. Once a blood clot is formed, the blood clot may break off under the squeeze of the beating heart and then flow in the direction of blood flow, most easily reaching the blood vessels in the brain, causing cerebral blood vessel blockage, which eventually leads to necrosis of brain tissue, leading to stroke.

Patients may develop hemiplegia, aphasia, and their ability to live is severely affected.

The high incidence and mortality of stroke in China has attracted widespread attention. It is especially important to be aware that 10 out of every 100 people with atrial fibrillation will have a stroke. Therefore, atrial fibrillation should not be taken lightly.

Once diagnosed, they should receive it promptly**. What physical symptoms might be warning signs of atrial fibrillation? Due to individual differences, when atrial fibrillation occurs, some patients will feel the beating of the heart, like a small rabbit beating, very irregular, irregular, fast and slow; Some people experience palpitations, commonly known as palpitations; Since the heartbeat is not rhythmic, the blood flow in the patient's heart is different from that of a normal person.

Answer]: E ventricular fibrillation can cause cardiac arrest, once the occurrence of empty hands should be done immediately asynchronous DC defibrillation next to the branch, at the same time with chest compressions and artificial respiration, keep the airway unobstructed, quickly complete the blind to establish venous access, and intravenous resuscitation and anti-arrhythmic drugs and other rescue measures.

The increase in the concentration of K+ in extracellular fluid during hyperkalemia inhibits the influx of Ca2+ in myocardial repolarization phase 2, resulting in a decrease in the concentration of intracellular Ca2+ in cardiomyocytes, a decrease in excitoline-contraction coupling, and a decrease in contractility.

Thus, although both hyperkalemia and hypokalemia can cause ventricular fibrillation, the heart eventually stops in diastolic during hyperkalemia.
