Development and validation of a novel method to derive central aortic systolic pressure from the radial pressure waveform using an N-point moving average method.

摘要

The purpose of this study was to develop and validate the novel application of a simple n-point moving average (NPMA)-a mathematical low pass filter-to noninvasively derive central aortic systolic pressure (CASP) from the radial artery pressure waveform (RAPWF) in humans.
