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). Web19 rows · Feb 12, 2024 · One of the most useful and commonly used diagnostic tools is electrocardiography (EKG) which measures the heart’s electrical activity as waveforms. …

The number of terms in the Fourier sum is indicated in each plot, and the square wave is shown as a dashed line ... WebThe sine wave is important in physics because it retains its wave shape when added to another sine wave of the same frequency and arbitrary phase and magnitude. It is the only periodic waveform that has this property. This property leads to its importance in Fourier analysisand makes it acoustically unique.
