Atrial fibrillation, short for atrial fibrillation, is an extremely common rapid cardiac arrhythmia. No underlying cause of atrial fibrillation has been found, but diseases or factors associated with atrial fibrillation include high blood pressure, coronary artery disease, heart surgery, heart valve disease, chronic lung disease, heart failure, cardiomyopathy, congenital heart disease, pulmonary embolism, hyperthyroidism, pericarditis, and combinations of other types of arrhythmias. Alcoholism, chronic stress, electrolyte or metabolic imbalance, and severe infections may also cause atrial fibrillation. 1.How to detect atrial fibrillation early If you always feel that your heart beats turbulently or your heart beats faster, feel tired easily, feel dizzy, have chest discomfort or shortness of breath, then you need to go to the hospital to check whether you have atrial fibrillation. Atrial fibrillation is not difficult to diagnose. The electrocardiogram (ECG) during an episode of atrial fibrillation is the basis for the diagnosis. If the episodes are short and frequent, the diagnosis can be confirmed by dynamic electrocardiogram. 2, pay attention to the potential danger of atrial fibrillation Although some patients with atrial fibrillation may have no symptoms at all or only minor discomfort, the potential danger of atrial fibrillation – thromboembolic complications still exist. Thrombosis and embolism are the most serious dangers of AF. In atrial fibrillation, blood tends to stagnate in the atria due to the loss of atrial contraction, and blood clots can form in the atria. If the blood clots are dislodged, they can flow throughout the body with the blood, leading to cerebral embolism, limb artery embolism (in severe cases, even need to amputate the limbs), and so on. The incidence of thromboembolic events in patients with atrial fibrillation is 5 to 17 times higher than that of normal people. Fast heart rate and irregular rhythm caused by atrial fibrillation will make the patient feel palpitations, which significantly reduces the quality of life of the patient; loss of atrial systolic function and tachycardia caused by prolonged increase in heart rate can lead to or aggravate heart failure. In addition, atrial fibrillation itself can increase mortality. 3, choose what method of treatment of atrial fibrillation At present, the treatment of atrial fibrillation mainly has two aspects of drug treatment and non-pharmacological treatment. Anticoagulation of atrial fibrillation mainly applies warfarin. The success rate of drug therapy is at most about 50%. Non-pharmacological treatments mainly include electrical cardioversion, surgery and catheter radiofrequency ablation. Electrical cardioversion is a method of direct current shock to restore atrial fibrillation to sinus rhythm, which has the advantage of a high rate of successful reversal, but does not have the effect of maintaining sinus rhythm. Surgery is currently used for patients with atrial fibrillation who require surgical treatment for other heart diseases. Surgery is effective, but open-heart surgery is too traumatic. Catheter radiofrequency ablation for atrial fibrillation has been carried out for several years in large cardiac centers at home and abroad, and is a minimally invasive procedure that can achieve the goal of eradication.
