The so-called atrial fibrillation is that the heart of a normal person beats 60-100 times per minute. When atrial fibrillation occurs, the atria become agitated 350-600 times per minute, and this agitation is so irregular that the atria cannot contract effectively. This results in panic, dizziness, fatigue, and in severe cases, shortness of breath, especially noticeable during activities such as walking up stairs, and in a few cases, transient blackening of the eyes. Harm: Atrial fibrillation is a common arrhythmia that not only affects quality of life, but also leads to disabling and fatal complications such as stroke or heart failure. Causes: With the arrival of the aging population, the incidence of atrial fibrillation is increasing year by year. There are two main reasons why the elderly become the high-risk group of atrial fibrillation, one is because their heart function has gradually deteriorated, and the other is because after entering the stage of old age, it can be accompanied by hypertension, diabetes mellitus, coronary artery disease and other cardiovascular diseases, which are the common triggers of atrial fibrillation. According to statistics, the incidence of atrial fibrillation increases dramatically with the age of the population, and atrial fibrillation is very common among the elderly, and the incidence of atrial fibrillation among people over 65 years of age can reach up to 5%. According to statistics, the incidence of atrial fibrillation increases sharply with age. The clinical symptoms of AF are varied and different. Although some patients may not have any feelings and symptoms (called asymptomatic atrial fibrillation), but the harm of atrial fibrillation still exists (such as cardiac insufficiency and thromboembolic complications), part of the patient because of the lack of obvious symptoms by the patient and family members neglected, so that the condition is delayed. Six signals of atrial fibrillation: 1, chest inexplicably thumping, as if the sound of thunder or the sound of fish jumping into the water. 2, pulse strength changes. 2, the pulse appears strong and weak changes, sometimes feel missed a beat. 3.Frequent symptoms of chest tightness and chest pain. 4. Feeling short of breath when exerting oneself a little. 5, easy to feel fatigue, exercise is not as good as before. 6, fainting, dizziness and other symptoms. When the above symptoms occur, do not be negligent, this may indicate that atrial fibrillation has occurred, should go to the hospital in time for examination and treatment. Radiofrequency ablation of atrial fibrillation is an interventional procedure, which is very traumatizing, with only two puncture points in the right and left femoral veins (thigh roots). The procedure is performed under local anesthesia and the patient is awake throughout the procedure and can tell the doctor if he/she has any discomfort. This minimizes discomfort, risk and pain. For a patient with paroxysmal atrial fibrillation, the procedure takes less than 1 hour, and for a patient with persistent atrial fibrillation, the procedure takes only 1.5 hours. After the procedure, the patient needs to lie down for 12 hours, and can get out of bed, and can be discharged from the hospital after observing for 1 day, with no recurrence and no complication.
