WebAtrial flutter originates in an ectopic pacemaker in the atria, typically depolarizing at a rate between 250 and 400 beats/minute (the average rate is approximately 300 beats/minute). The atria respond to this rapid stimulation by producing V-shaped waveforms resembling the teeth of a saw. The sawtooth waveforms are called flutter waves (F waves). WebJun 10, 2012 · During atrial flutter the atria depolarize in an organized circular movement. This is caused by re-entry. The atria contract typically at around 300 bpm, which results in a fast sequence of p-waves in a sawtooth pattern on the ECG. For most AV-nodes this is way too fast to be able to conduct the signal to the ventricles, so typically there is a ...
