title: [Analysis of diastolic heart function. Principles and considerations on the use of 2 harmonics].
abstract: In this study the authors have briefly exposed the mathematical bases about the application of the Fourier transform in cardiac radioisotopic examinations. It has pointed out the usefulness of two harmonics for clinical applications.
