Its typical ECG performance is normal atrial wave (P wave) is replaced by f wave with irregular ventricular rhythms. f wave usually shows as a small amplitude of baseline oscillation. Its frequency usually ranges from 300 to 600 bpm, with changeable amplitude, shape and period. In comparison, the frequency of atrial flutter is 250 ~ 350 bpm, with stable shape and period.In the absence of negative conduction factors, the ventricular rate of a tpical atrial fibrillation is usually from 100 to 160 bpm. In patients with W-PW ...
