Electrocardiography: Atrial Fibrillation - e
... Symptoms In atrial fibrillation, symptoms depend on the rate at which the ventricles are beating. A mild increase in the ventricular rate, less than about 120 beats per minute, may produce no symptoms. Higher rates cause unpleasant palpitations, feelings of lightheadedness or faintness, weakness, la ...
