What is the relationship between myocardial infarction and arrhythmias? In what way?

Myocardial infarction often causes some arrhythmias, but arrhythmias often do not lead to myocardial infarction. Myocardial infarction is a persistent blood disorder in the coronary arteries, resulting in the necrosis of some myocardial cells due to ischemia and hypoxia. However, arrhythmias refer to abnormal rhythms of the heart's beating and abnormal conduction of the cardiac conduction system, such as common heart rhythm abnormalities such as atrial premature contractions, ventricular premature contractions, atrial fibrillation and right bundle branch block, atrioventricular block and other conduction system abnormalities.

According to the latest news I have learned, myocardial infarction has a certain correlation with arrhythmia, but after the occurrence of acute myocardial infarction, due to the instability of some myocardial necrosis and necrotic myocardial cell membranes, some arrhythmias, such as ventricular premature contractions and ventricular tachycardia, are easy to occur. The most common reason for the high mortality rate of most acute myocardial infarctions in the first few days is that malignant arrhythmias are prone to occur after myocardial infarction, so patients with acute myocardial infarction should be monitored electrocardiogram and actively manage arrhythmias such as premature ventricular contractions and ventricular tachycardia.

However, there are many causes of arrhythmias, and patients with myocardial infarction are only part of the cause. Arrhythmias can occur in a variety of heart diseases, high blood pressure, thyroid disease, and even non-organic diseases. On the other hand, if there is no coronary heart disease, arrhythmia does not induce coronary heart disease and myocardial infarction, but if there is a problem with the coronary arteries, angina can be induced if persistent tachyarrhythmia occurs.

If angina persists and does not resolve, acute myocardial infarction may occur. Arrhythmia is generally to determine whether there is a **, assess whether the arrhythmia has an impact on the prognosis, whether it affects the quality of life, etc., and then decide whether to be active**, myocardial infarction is also known as myocardial infarction, myocardial infarction refers to coronary artery occlusion, interruption of blood flow, severe continuous ischemia leading to partial myocardial necrosis.

Finally, as for the above question of how myocardial infarction is related to arrhythmia and what it manifests, I will analyze it here today.

Arrhythmia is one of the symptoms of myocardial infarction, and some headaches, vomiting, and angina may occur.

There is a correlation between myocardial infarction and arrhythmias, and angina may be induced if persistent rapid arrhythmias occur; If angina persists and does not resolve, an acute myocardial infarction may occur.

Myocardial infarction means that the heart has some steal arrest, at this time the blood clotting together will form such an infarct arrhythmia, that is, the heartbeat is erratic, sometimes fast and sometimes slow, this is arrhythmia, like when we are usually emotional, this aspect can be well expressed.

Arrhythmias must be eliminated in time to avoid becoming severe arrhythmias or even sudden death. In the case of ventricular fibrillation or sustained polymorphic ventricular tachycardia, asynchronous or synchronous DC defibrillation or cardioversion should be used as soon as possible, and synchronous DC cardioversion should be used as soon as possible when the efficacy of the ventricular tachycardia drug Yu He's is not satisfactory. Once premature ventricular contractions or ventricular palpation hypertachycardia are detected, lidocaine 50 100 mg intravenously is immediately given, repeated every 5 to 10 minutes, until the premature contractions disappear or the total amount has reached 300 mg, and the vertical intravenous infusion is maintained.

Amiodarone may be used for recurrent ventricular arrhythmias. Bradyarrhythmias can be treated with atropine intramuscularly or intravenously. Patients with second- or third-degree AV block who develop hemodynamic compromise with a temporary artificial pacemaker are indicated.

When supraventricular tachyarrhythmia cannot be controlled by drugs such as verapamil, diltiazem, metoprolol, digitalis preparations, and amiodarone**, synchronous direct current conversion can be used**.

The description of arrhythmia after acute myocardial infarction is incorrect ().

a.It usually occurs 1 week after the onset of illness.

b.It is especially common in 24 hours ago.

c.Various arrhythmias can occur.

d.Ventricular arrhythmias are the most common.

Correct Huikai Answer: a

Answer]: A In heart failure, the ECG generally does not have specific changes in the brucella plexus. The most common arrhythmia in acute anterior myocardial infarction is premature ventricular contractions.

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.

There are actually many causes of myocardial infarction, which are caused by various factors, such as overwork may overburden the heart, myocardial infarction or excessive mood swings may also be induced, and some people overeating may cause blood lipids to rise rapidly in a short period of time, resulting in increased blood viscosity and myocardial infarction. Some sudden cold may also cause myocardial infarction, and long-term staying up late and constipation may induce acute myocardial infarction. Before the advent of myocardial infarction, the body will also have some manifestations, at this time the patient may have chest pain, which is also a more typical symptom, but also accompanied by dyspnea, wheezing, nausea and vomiting and other problems, a small number of patients may have pain in the upper abdomen, and there may be some discomfort in the whole body, fever, some patients will also have arrhythmia, heart failure and other serious conditions may have the problem of hypotensive shock.

According to the data, many young people are now suffering from heart attack, which is also because the lifestyle of young people is becoming more and more unhealthy, many people often stay up late because of work, and some white-collar workers are often sedentary and do not exercise enough, coupled with excessive pressure in life, which has caused certain damage to the body of young people to a certain extent. One of the most important reasons is that many people's emotional problems are very big now, too many negative emotions cause everyone to be unhappy, and it is very scary to have all kinds of retaliatory behaviors.

If you want to prevent myocardial infarction, you must avoid some bad habits, such as smoking, drinking alcohol and diet, and reduce the intake of some overly refined carbohydrates as much as possible, supplement an appropriate amount of high protein and fat, and usually do a moderate amount of physical exercise to promote blood circulation and improve the body's resistance. It is also necessary to adjust the daily routine, avoid staying up late, go to bed early and get up early, combine work and rest, and at the same time maintain a good attitude and do not be in a state of tension and anxiety.

Finally, the harm caused by myocardial infarction to everyone's body is still very large, if there is a sudden myocardial infarction, in fact, it is not the problem that may cause death, so we must pay attention to the problem of myocardial infarction.

Unhealthy diet, eating too much, oily and sugary, salty and greasy food, irregular work and rest, staying up late and drinking and not exercising will all lead to heart attack, and the body will have dizziness, nausea, vomiting, weakness, and decreased appetite.

Most of them are caused by diet, irregular diet, not paying attention to rest, the body will be uncomfortable before the heart attack, and there may be some heart pain and difficulty breathing.

Answer]: B In the early stage of acute myocardial infarction, ventricular arrhythmia is the most common among all lead-burning arrhythmias, especially premature ventricular contractions, such as frequent premature ventricular contractions (more than 5 times per minute), pairwise or short-sized ventricular dermal tachycardia, multi-source or falling in the vulnerable phase of the previous heartbeat (R on the T wave), which is often a precursor to ventricular fibrillation.
