What is atrial fibrillation?

Atrial fibrillation, referred to as atrial fibrillation, is one of the most common arrhythmia in clinical work. There are many reasons for atrial fibrillation, such as hypertension, coronary heart disease, pulmonary heart disease, hyperthyroidism and so on. The loss of orderly electrical activity in atrial fibrillation leads to atrial fibrillation disorder, which leads to the loss of effective contraction and relaxation. Therefore, in atrial fibrillation, not only the heart rate is disordered, but also the atrial ejection function is lost by 20%, and patients may have palpitation discomfort, cardiac function deterioration and even thrombosis. Clinically, the main manifestations of patients are sudden palpitation and palpitation, especially the sudden appearance of heart rate 100 beats/min, which is 150- 160 beats/min. The patient will have obvious palpitation, palpitation and even induce transient ischemic attack, and the patient will suddenly faint. In addition, repeated tachycardia will worsen the cardiac function of the original patients, and some patients will have acute left heart failure. Therefore, in many cases, rapid arrhythmia often occurs after accurate attack, especially atrial fibrillation. After atria lose effective contraction and relaxation, slow blood flow induces thrombosis, so the primary disease of many patients with cerebral thrombosis may be atrial fibrillation, and cerebral thrombosis may also be induced after embolus falls off, but peripheral arterial embolism, such as lower extremity arterial embolism and renal artery embolism, may also occur.
