Abstract
A method for recording dp/dt by using a standard catheter system was developed after pressure pulses had been analysed in terms of their Fourier series. A comparison between the recorded dp/dt and a reference system was then made. It was concluded that practical and useful representation of the form and reasonably accurate determination of the magnitude of peak dp/dt are possible with such a system.Keywords
