Myocardial infarction predicts arrhythmias for ventricular fibrillation

Myocardial infarction is a particularly serious disease, which causes serious damage to the patient's physical health, and once the onset of the disease, palpitations, shortness of breath and irritability appear, and will disturb the patient's daily life. We should pay attention to our own health, pay attention to myocardial infarction, and need to understand the precursor manifestations of the disease in life.

1. Patients with myocardial infarction will have symptoms of fatigue and chest discomfort a few days before the onset of the disease, and palpitations, shortness of breath and irritability will appear during the activity, accompanied by angina pectoris and other symptoms, among which the new angina pectoris and the aggravation of the original angina pectoris are the most obvious. The symptoms of angina pectoris are more frequent than in the past, and the severity is particularly severe, and patients continue to have the symptoms, which can cause more trouble in their lives.

2. The pain symptoms can not be ignored, the location and nature of the pain are very similar to angina, which is easy to occur during quiet or sleep, and the degree of pain is particularly serious and widespread. Patients with severe disease with symptoms such as sweating and fear.

3. Some myocardial infarctions will have systemic symptoms in the early stage, accompanied by fever and general fatigue. In severe cases, tachycardia and leukocytosis are likely to occur, which are mostly caused by the absorption of necrotic substances.

Patients with myocardial infarction should be on bed rest and should eat a diet based on digested food. If necessary, sedation and oxygen inhalation can be performed, and oxygen can be given by nasal cannula, and the oxygen flow rate is generally 2-4L. For patients with severe pain, the rational use of analgesic drugs should pay attention to the drop in blood pressure and respiratory depression.

Intravenous infusion of nitroglycerin can be used to control the progression of the patient's disease.

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.

Senhan answer]:b

In acute myocardial infarction, arrhythmia mostly occurs in the early stage of the onset, and can also occur within 1 or 2 weeks of the onset, with premature ventricular contractions, ventricular tachycardia, ventricular fibrillation, leading to cardiac arrest and sudden death. Bradyarrhythmias such as bradycardia and atrioventricular block are more common in patients with inferior infarction in the early stages of the disease, and most of them can be recovered, and permanent pacemakers are required for all patients**. Therefore, the answer to this question is b.

Answer]: Paroxysmal ascending ventricular tachycardia refers to tachycardia originating from the atrium or atrioventricular junction area of the wild stool, most of which are caused by reentry agitation, and a few are caused by increased automaticity and triggered activities, and are easy to cause ventricular fibrillation if not properly handled.

Answer]: B cardiac biarrhythmia is the main cause of death in patients with acute myocardial infarction, which mostly occurs within 1 or 2 days after the illness, and the incidence rate is the highest in the first 24 hours, and ventricular arrhythmia is the most common. Ventricular tachycardia often predicts the development of ventricular fibrillation.

Cons and Answer] :d

Arrhythmia is the main cause of death in patients with acute myocardial infarction, which mostly occurs within 1 to 2 days after illness, with the highest incidence in the first 24 hours, and ventricular arrhythmia is the most common.

Answer]: C lidocaine belongs to class B antiarrhythmic drugs, and the posture pants are ineffective against the atrial muscle of the short action potential time, so it is only used for ventricular arrhythmias. It is mainly used for ventricular arrhythmia caused by acute myocardial infarction.
