Atrial fibrillation - symptoms and methods of its elimination
Many patients ask a question - what isatrial fibrillation? This is a violation of the contractile function of the heart, which is accompanied by fibrillation of the muscle fibers of the atria. Atrial fibrillation is characterized by fast and irregular electrical atrial pulses, whose frequency can reach 350-600 per minute, as a result of which ventricular contractions are also irregular. Systematic violations of the rhythm of contraction of the heart muscle can lead to chronic circulatory failure. Atrial fibrillation is the most common form of arrhythmia. The main causes that cause it are myocarditis, heart failure, cardiomyopathy, cardiosclerosis, hypertension, etc. Also, atrial fibrillation can develop against a background of thyrotoxicosis, alcohol poisoning, adrenomimetics and cardiac glycosides.
Atrial fibrillation has different symptoms, independing on its form (paroxysmal, constant, tachysystolic, bradiscital) and on the state of the heart muscle. The most severe manifestation of tachysitolytic form of arrhythmia (rapid heartbeat, pain in the heart, shortness of breath, which increases with physical exertion), as well as paroxysmal atrial fibrillation, the symptoms of which are mainly manifested as weakness, sweating, trembling, fear, polyuria, dizziness, fainting. Often, patients complain of shortness of breath and a feeling of pain in the heart, sometimes there is anemia of the visible mucous membranes and cyanosis of the lips.
Atrial fibrillation: symptoms and treatment
Treatment of the disease is aimed at restoringheart rhythm, prevention of recurrence of atrial fibrillation, prevention of thromboembolism. In medical practice to prevent the development of paroxysms of arrhythmia use quinidine, novocaineamide, propanorm, cordarone. Less effective is the use of verapamil, digoxin, anaprilin. The mechanism of their action is aimed at normalizing the contractile activity of the myocardium, improving the health of patients (reduce shortness of breath, weakness, palpitations). With insufficient effectiveness of the use of medicines, cardiologists often prescribe an electric cardioversion (impulse electric discharge to the heart area in order to improve the heart rhythm), with paroxysms disappearing in 90% of cases. Atrial fibrillation, the symptoms of which last more than 2 days, increases the chances of developing thromboembolism. To prevent the formation of thrombi prescribed warfarin. Patients with a diagnosis - chronic form of atrial fibrillation, appoint atenolol, egilok, concor (adrenoblockers), diltiazem, verapamil, digoxin (antagonists of calcium ions). The effectiveness of treatment depends on the timely establishment of the underlying disease, which caused the development of rhythm disturbances. Radical methods that eliminate atrial fibrillation are the use of RF isolation of pulmonary veins. The focus of ectopic excitation, which is localized in the mouths of the pulmonary veins, is removed from the atria. The effectiveness of radiofrequency isolation in the treatment of atrial fibrillation is about 60%. With a permanent or recurrent form, radiofrequency ablation (burning) of the atrioventicular node of the heart is prescribed with the implantation of a permanent pacemaker.
The basis of primary prevention istimely treatment of diseases dangerous for the development of atrial fibrillation. Secondary prophylaxis is aimed at observing the doctor's recommendations regarding antirechered therapy, limiting physical and psycho-emotional stress, abstinence from the use of nicotine and alcoholic beverages.
