Atrial fibrillation, also called atrial fibrillation, is an irregular beating of the heart that is not regular, and the heart rate of atrial fibrillation is much greater than the number of pulse beats compared to the number of pulses, but the specific value should be determined according to the severity of atrial fibrillation, for example, if the patient’s heart rate of atrial fibrillation is 150 beats per minute, the pulse may be about 80-90 beats per minute. Once atrial fibrillation occurs, the cause of atrial fibrillation should be clarified through electrocardiogram, cardiac ultrasound, coronary CTA, coronary angiography and other examinations, and active treatment should be given. Medications such as metoprolol, betalactone, amiodarone, etc. are available for medication to relieve the symptoms of atrial fibrillation.
