The arterial waveform is clearly not a simple sine wave as described above, but it can be broken down into a series of many component sine waves. The arterial pressure wave consists of a fundamental wave (the pulse rate) and a series of harmonic waves.

The most widely used device in clinical studies for PWA measures the arterial pressure waveform at the radial artery and applies a validated generalised transfer function to provide the central pressure
pressure pulse waveform. The arterial pulse waveform has been studied by breaking it down into its component harmonics much like a musical wave. The majority of the energy of the pulse is contained in its first five harmonics.
