Atrial flutter and atrial fibrillation

Atrial flutter and atrial fibrillation are arrhythmias that occur in the atrium and have a higher impulse frequency than atrial tachycardia. When the frequency of atrial ectopic pacing points is 250-350 beats / min, the atrial contraction is fast and coordinated as atrial flutter. If the frequency is> 350 beats per minute and irregular, it is atrial fibrillation. Both can have both paroxysmal and chronic persistent types. This disease is a common arrhythmia in cardiology clinics. It often occurs in patients with rheumatic heart disease, coronary heart disease, hyperthyroidism, cardiomyopathy, hypertension, etc. It can also occur in patients without organic heart disease (idiopathic atrial fibrillation).
