Sampling an aortic pressure waveform at 80 ms (A), 40 ms (B), 20 ms (C), and 10 ms (D) as compared to sampling at 1 ms. These high temporal resolution 1 ms data were acquired in the aorta of a pig with a fiber optic intravascular pressure sensor. For (A), (B), and (C) the waveform was downsampled to demonstrate that the shape of the waveform is highly dependent on adequate sampling of the data.
