PTC1 and PTC2: New Indices of Blood Pressure Waveforms and Cardiovascular Disease

New cardiovascular indices based on nonlinear spectral analysis of arterial blood pressure waveforms

A new method for analyzing arterial blood pressure is presented in this article. The technique is based on the scattering transform and consists in solving the spectral problem associated to a one-dimensional Schrödinger operator with a potential depending linearly upon the pressure. This potential is then expressed with the discrete spectrum which includes negative eigenvalues and corresponds ...

Indices of blood pressure variability and cardiovascular risk.

Letters to the Editor will be published, if suitable, as space permits. They should not exceed 1000 words (typed double-spaced) in length and may be subject to editing or abridgment. To the Editor: I read with interest the article by Hansen et al 1 evaluating the relation between blood pressure (BP) variability and risk. The prognostic value of BP variability, expressed as SD, was previously ev...
