Atrial fibrillation is dangerous complications!


Atrial fibrillation is dangerous complications!Atrial fibrillation - the most commonabnormal heart rhythm, which in itself is not dangerous to human life. Frequently, following each other without a break, reducing the two upper chambers of the heart, the atria have little impact on the general circulation. The ventricles continue to contract normally, and blood is pumped through the vessels, bringing oxygen and nutrients to all parts of the body. Violation of atrial contraction rhythm very rarely leads to a malfunction of the ventricles, which in fact represents the greatest threat to life. Why, then, atrial fibrillation attracts so much attention of doctors? What is the danger for humans?

What is it flickers and why?

Atrial fibrillation, or as it is called,Atrial fibrillation is characterized by frequent chaotic contraction of the atria, reaching frequencies of 350-700 beats per minute. In fact, the two upper parts of the heart, feeding blood into the ventricles cease to decline, marked only the twitching of the individual fibers of the heart muscle. The blood flows into the ventricles of "gravity" and the ventricles continue to work at their own pace, shrinking much less than the atria.

Causes of atrial fibrillation lie in defectsworking pacemaker, is responsible for the coordinated contraction of the heart, in violation of the conduction fibers that delivers the nerve impulses from the pacemaker to the myocardium, to increase the excitability of heart muscle contraction responsible for these pulses. All this is quite difficult for the average person is more important to know what to disruption of heart rhythm can cause stress, smoking, alcohol consumption and abuse of products containing caffeine. Even banal viral infection can cause a malfunction of the heart, not to mention hypertension, heart disease, lung and thyroid.

Why treat arrhythmia?

Atrial fibrillation affects roughly one in 200 minutesinhabitant of the Earth, and the older the person, the higher the risk of his arrhythmia. People aged 50-60 years, atrial fibrillation occurs with a frequency of 3.5%, and among the 80-90 year old rhythm disorders is almost one in ten. Interestingly, women are less likely than men suffer from arrhythmia, but they have rhythm disturbance is more severe and difficult to correct.

Atrial fibrillation, although not life-threateningHuman directly, significantly reduces quality of life. Just look at the symptoms, to be sure - life with arrhythmia is not sugar. "Inaction" atrial leads to the fact that in the ventricles goes a little blood and, therefore, suffers from the general circulation and disrupted the whole organism.

The clearest symptoms of atrial fibrillation:

  • cardiopalmus;
  • chest pain;
  • general weakness;
  • dizziness or fainting;
  • sweating;
  • feeling short of breath;
  • panic and fear for their own lives;
  • frequent urination.

The attacks of atrial fibrillation may be rare or frequent, sometimes arrhythmias are permanent, and then to treat them a must.

The dangerous atrial fibrillation?

In half of the atrial fibrillation is notviolates the general condition of patients, seizures go unnoticed, but this does not detract from the dangers of the disease. The fact is that the lack of a coordinated contraction of the atria leads to stagnation of blood in them and is fraught with the formation of blood clots - clots. Because atrial thrombi reach the ventricles, then entered into the artery of the brain and other vital organs, causing them acute circulatory problems.

  • Atrial fibrillation is one of the mainthe causes of cerebral strokes. It is believed that the presence of cardiac arrhythmias is 5 times increase the risk of cerebral accident, ends in death or disability.
  • Getting in the coronary arteries, the blood clot causing myocardial infarction.
  • Once in the blood vessels of the intestines, the blood clot becomes the cause of his gangrene and peritonitis development of severe, often has a fatal outcome.

Doctors believe that the development of heavycomplications enough to attack of atrial fibrillation lasted for 2 days. At the same time according to statistics 30% of asymptomatic episodes last for much longer. Here in this lies the main threat to the world the most common cardiac arrhythmia.
