Atrial fibrillation, known as atrial fibrillation or atrial fibrillation, is the loss of normal, regular, coordinated, effective contractile function of the atria and its replacement by irregular fibrillation ranging from 300-600 beats per minute. There are various ways of staging atrial fibrillation, classifying it into acute atrial fibrillation and chronic atrial fibrillation. Acute atrial fibrillation episodes generally cannot be diverted by self-help and require prompt medical attention, but appropriate measures can be taken to relieve them. During an acute AF attack, try not to stress and sit down and rest first to avoid aggravating symptoms or inducing other diseases. Patients with a history of atrial fibrillation who feel significant symptoms on their own can first take beta-blockers such as metoprolol for relief and rush to the hospital for treatment as soon as possible. If the ventricular rate is greater than 150 beats/minute with persistent chest pain, systolic blood pressure is less than 90 mmHg, and symptoms such as heart failure and unconsciousness are present at the time of seeking medical treatment, DC electric cardioversion should be used, and anticoagulants such as low molecular weight heparin should be given. For patients who do not need electric cardioversion, if palpitations, shortness of breath, weakness, chest tightness and other symptoms are obvious, the ventricular rate needs to be controlled quickly with drugs, commonly known as furioside C, diltiazem, propranolol, metoprolol, etc., and need to monitor electrocardiographic monitoring. Patients with atrial fibrillation should be actively medicated and reviewed regularly. Stop smoking and limit alcohol on a daily basis and avoid caffeine-containing substances such as tea and coffee. Pay attention to the combination of work and rest, regular life, ensure sufficient rest, and avoid staying up late. Maintain an optimistic mood and try not to get excited to avoid triggering atrial fibrillation attacks.
