Atrial Fibrillation is a heart attack.

Atrial fibrillation (AF) is a heart disease, a common arrhythmia, referring to atrial fibrillation disorder. This fibrillation will make the atrium lose effective contraction and relaxation, atrial pumping function deterioration or loss, coupled with the atrioventricular pair rapid atrial excitation decreased conduction, resulting in extremely irregular ventricular response. Therefore, can cause patients to show ventricular rate disorder, cardiac function damage and atrial wall thrombosis. The severity of AF symptoms by ventricular rate speed influence, ventricular rate is not fast when there are no symptoms. When ventricular rate exceeds 150 beats/min, patients will feel palpitations, chest tightness and shortness of breath, angina pectoris, even heart failure, and systemic embolism. AF was converted to sinus rhythm by drug conversion, electrical conversion and catheter ablation. For persistent AF, drugs to slow ventricular rate should be selected and thromboembolism prevention should be paid attention to. Drugs to control ventricular rate include β-receptor antagonists, calcium channel blockers or digoxin, etc.
